Why Your Shot Takes Seconds to Appear, and a Stage-by-Stage Way to Shorten the Wait

If you swing and then wait a couple of seconds for the ball to show up on screen, you are not imagining it. Shot delay exists on every launch monitor, and how long it lasts depends on the unit, the connection, the computer, the projector and the software you run. Most of the time the wait is a sum of several smaller waits, and only one or two of them are usually the big ones.

This guide splits that wait into five stages, gives typical figures for common launch monitor types, and shows a phone video test that points at the slow stage. Once you know which stage is slow, the fixes get much narrower: a laptop that is throttling, a Wi-Fi link that drops, a projector stuck in a processing-heavy picture mode, or course software that loads far more scenery than it needs.

The typical figures below come from owner reports and maker figures, not lab tests, and they vary with software, connection and PC. Treat them as ballpark numbers and compare them with your own timing before deciding something is wrong.

How we put this together: we compared published manufacturer specs, retailer listings and owner reports. Links on this page may earn us a commission.

Typical impact-to-screen times by launch monitor type

Start here to answer whether your wait is normal. Your setup may land above or below these figures, so use them as a reference point rather than a pass mark.

Type	Example models	Typical impact to ball flight on screen	Source note
Side-of-ball photometric	Original SkyTrak	About 2.5 to 3 seconds	Owner reports
Side-of-ball photometric	SkyTrak+	About 2 seconds	Owner reports
Other consumer units	Foresight GC3 / GCQuad, Bushnell Launch Pro	Commonly reported around 1 second or less	Owner reports
Overhead camera	Uneekor EYE XO / XO2	Commonly reported as near-instant, under 1 second	Owner reports
Radar	FlightScope Mevo+, Garmin Approach R10	Commonly reported 1 to 2+ seconds, depending on app and connection	Owner reports
Other consumer units	Rapsodo MLM2PRO	Owners report a short wait, similar to other consumer units	Owner reports

Owners report the original SkyTrak at roughly 2.5 to 3 seconds and the SkyTrak+ at about 2 seconds. The Foresight GC3 and GCQuad and the Bushnell Launch Pro are commonly reported at around a second or less. Overhead camera units such as the Uneekor EYE XO and XO2 are commonly reported as near-instant. Radar units, including the FlightScope Mevo+ and Garmin Approach R10, are commonly reported at one to two seconds or more, depending on the app and the connection. Owners describe the Rapsodo MLM2PRO's wait as short and similar to other consumer units.

Use the table as a rule of thumb. If your wait is much longer than the typical figure for your unit, something in your setup is adding time. If it matches the figure, you are probably at the design floor for that unit, and the fixes below will only shave off what the design leaves in.

Where the time goes: five stages

Think of impact-to-screen time as a budget with five lines in it. Each stage can add time, and the stages that depend on your own setup are the ones worth attacking first. The stages below run in order, from the moment the ball leaves the club to the moment the picture changes.

Capture

The unit has to see the ball leave before it can report anything. Radar units track the early flight for a period before they report, so their wait depends partly on how long they need to watch the ball. Camera units capture images in milliseconds, which is one reason overhead systems are commonly reported as very quick. Capture time is mostly a design property of the unit, so there is little you can change here.

On-device processing

Photometric and camera units both turn what they see into speed, launch and spin numbers. This is the main design-based part of the delay. You cannot tune it through settings, and no PC upgrade removes it. If this stage accounts for most of your wait, the only real lever is choosing a different launch monitor.

Transfer

Data moves from the unit to a phone, tablet or PC over Bluetooth, Wi-Fi direct, a Wi-Fi network, USB or ethernet, depending on the model. Weak or congested wireless adds delay, and in bad cases it adds dropped shots. If you use third-party software, a connector app that passes data from one program to another adds a step, and the cost depends on the connector and its version. Shot data mostly stays on your local link, so the internet connection is rarely the bottleneck. Our guide on whether a simulator needs internet covers that question in more detail.

Software physics and rendering

Ball flight calculation is quick. The slow parts are usually loading scenery, playing camera animations and drawing frames on a graphics card that is already busy. A course with dense foliage and long camera swoops can add noticeable time before the ball appears to move, even though the physics itself finished long before.

Display

A projector adds its own input lag before the picture changes. Figures published for many projectors in game mode fall around 16 to 40 ms at 1080p and 60 Hz. With picture processing turned on, the lag can climb past 100 ms. A single 60 Hz frame lasts 16.7 ms, so display lag is small next to processing that takes seconds, but it stacks up when motion smoothing is switched on. Check your projector's spec sheet for the figure that applies to your model.

Time your own setup with a phone

You need a phone that can record at a high frame rate and a stand or tripod to hold it steady. A slow-motion mode is ideal. The test turns a vague feeling of lag into a number you can compare after each change.

1. Prop the phone so the ball and the screen are both in frame. Record at the highest frame rate available.
2. Hit five shots. In playback, count frames from impact to the first movement of the ball on screen.
3. Repeat in the launch monitor maker's own app, using range mode if it has one. The gap between the two averages is software and connector time.
4. Repeat with a wired connection, or with the device placed right next to the unit, to test transfer.
5. Plug the PC into a TV or monitor set to game mode, in place of the projector, to test display lag.

Frame rate sets the resolution of your count. At 30 fps each frame is 33 ms, at 60 fps it is 16.7 ms, and at 240 fps it is about 4.2 ms. A quick example: 120 frames at 60 fps is 2.0 seconds. Slow-motion footage at 240 fps gives you the finest count, so use it when your phone offers it.

Record each run in a simple table so you can see what each change did:

Reading your results

Once you have averages, the pattern usually points to one stage. Match your numbers to the situation below and work on that stage first.

• Native app fast, third-party sim slow. The problem sits in the software, the connector or the PC. Start with the connector version and the computer's spec before touching anything else.
• Both slow and wireless. Transfer is the likely culprit. Try network mode, move the router closer or add an access point, and use a wired connection where the unit supports it.
• Fast on a TV, slow on the projector. Projector processing is adding the time. Turn on game mode and check the picture settings for anything that adds processing.
• Everything matches the typical figure for your unit. You are at the design floor. Only a different launch monitor will change that number, so spend your effort on the software and the picture instead.
• Delay grows during a session. The usual suspects are heat, background downloads, laptop power saving or a memory leak. Restart the PC, check temperatures and see whether the wait drops back to its starting level.

Fixes at the launch monitor and connection

These fixes target capture and transfer, the two stages you can influence from the outside. Work through them in order and re-time after each change.

• Update the launch monitor firmware and the companion app. Older builds sometimes carry connection bugs that newer ones fix.
• SkyTrak+: compare direct mode and network mode. Network mode through a good router can be steadier, but check current SkyTrak guidance for which mode suits your setup. If the unit is also freezing, our SkyTrak freezing fixes cover that separately. For the unit itself, see the SkyTrak+ review.
• Bluetooth units: the Garmin R10 and Rapsodo MLM2PRO connect over Bluetooth according to their makers' listings. Keep the phone or tablet close to the unit, remove other paired devices nearby and close other apps on the phone.
• Wi-Fi: use 5 GHz where the unit supports it, keep the router close or add an access point, and avoid busy channels. Our guide to fixing Wi-Fi drops walks through the steps in order.
• Wired where the unit supports it. The Uneekor EYE XO is listed with an ethernet connection, and Foresight units can connect over USB. Check your model's manual for the options it offers.
• Use the current version of the connector app for any third-party software, and check its setup notes after each software update.

Fixes on the computer

The PC is the stage most people overlook. A laptop that is perfectly fine for browsing can be too slow for a course with heavy graphics, and a background download can stall a shot without any obvious sign.

• Meet the software's recommended spec, not the minimum. Our PC requirements by software guide lists what each program asks for.
• Plug laptops into power and set Windows to the best performance power mode. Battery saving can throttle the processor and the graphics chip together.
• Close background apps, cloud sync and browser tabs during play, and pause any game launcher downloads while you hit.
• Update GPU drivers from NVIDIA or AMD so the graphics card runs the way the software expects.
• If the frame rate drops during ball flight, lower the heaviest graphics settings first: shadows, grass and foliage density, and render scale. These are the settings that cost the most frames per second.
• Store the simulator software and courses on an SSD so course loads do not stall the start of each hole.
• If your current machine is the bottleneck, compare simulator computers and simulator laptops before you buy anything new.

Fixes at the projector or screen

The display stage is where small settings make a visible difference, because they change how the projector handles each frame before it reaches your eyes.

• Turn on game or low-latency mode, and turn off motion smoothing and frame interpolation. These two features add processing that you do not need for a golf swing.
• Digital keystone and some image enhancement features add processing. Where possible, correct the geometry physically with the mount instead of in the projector. Check your model's manual for which features add processing.
• Send the projector its native refresh rate, commonly 60 Hz. Some projectors offer 120 Hz or higher at 1080p for lower lag, so check whether yours does.
• Use a certified high-speed HDMI cable that supports your resolution and refresh rate. Long runs may need an active or fiber cable to hold a clean signal.
• BenQ markets its gaming short-throw models, such as the TK700STi, with low input lag in game mode. Check the current figure on BenQ's spec page before you buy or rely on it.
• For projectors matched to your room and budget, see low-lag projectors by room and budget.

Fixes inside the simulator software

Software settings do not change the physics, but they can change how soon the ball appears to move. Camera choices and replays are the biggest levers here.

• Camera behavior: shorter follow-camera transitions and fewer cut-scene angles make the ball appear to move sooner. Setting names vary by program, so look for them in the camera or view menu.
• Turn off replays or auto-replays between shots. A replay that plays before the next ball is ready adds a visible pause every time.
• Check ball-ready and next-shot timing. Some programs add a pause before the next shot, and that pause can be shortened or removed in the settings.
• Practice range modes load less scenery than full courses, so use them for quick sessions where you care about how fast the shot appears.
• Keep the program and course files updated. Developers often fix loading and camera issues in patches.
• For a broader checklist of what to look for in a program, see our guide to software features that matter at home.

Delay built into the hardware

Some delay is designed in, and no amount of tuning will remove it. Knowing where that line sits keeps you from chasing a setting that cannot help.

Photometric processing on lower-cost units takes time by design, and no PC upgrade changes that. Radar units need to track the ball for a moment before they can estimate its flight. Indoors, where the ball's flight is short, that tracking window can add uncertainty rather than speed. A radar unit is therefore not automatically the quick choice in a small room, even though it is a strong option in many other setups.

Time between shots is a separate number from impact-to-screen delay. It measures when the unit is ready to read the next ball. Both matter in a busy session, and a unit can be quick on one and slower on the other, so time them separately rather than assuming one tells you about the other.

If delay is a buying priority, look at the units owners describe as near-instant, such as overhead camera systems. Read owner reports for the specific software you plan to run, because the delay depends on the combination of unit, connection and program. For the trade-offs between the two designs, read our radar vs camera launch monitors comparison. You can also browse overhead launch monitors and launch monitors for simulators to narrow the field.

Worked example: from 4.5 seconds to about 2

This is an illustrative example built from typical figures, not a record of a real session. It shows how the method plays out with numbers, so you can follow the same logic with your own timings.

The setup is a SkyTrak+ connected over Wi-Fi direct to a three-year-old laptop running on battery. The projector sits in a bright cinema mode, and the course runs in third-party software. The phone test at 60 fps comes out like this:

• In the course software, about 270 frames from impact to ball movement, which is 4.5 seconds.
• In the SkyTrak range app, about 130 frames, which is 2.2 seconds.

That gap of about 2.3 seconds points to the computer, the projector and the connection. Working through the stages in order, the changes look like this:

1. Laptop on mains power and best performance mode. Example saving: about 0.8 seconds.
2. Projector switched to game mode. Example saving: about 0.1 seconds.
3. Shadows and grass lowered on the course. Example saving: about 0.8 seconds.
4. Network mode through a router placed next to the bay. Example saving: about 0.6 seconds.

Those four changes add up to about 2.3 seconds. Taking that from 4.5 seconds leaves about 2.2 seconds, which matches the range app figure. The remaining wait sits close to the unit's design floor, so further gains would need a different program or a different launch monitor, not more tuning.

The useful lesson is the order. The laptop and the graphics settings were the largest savings, and the projector setting was the smallest. A player who started by buying a faster projector would have spent money on the stage that mattered least in this scenario.

Lag questions from simulator owners

The questions below cover points the sections above do not fully settle. Each answer stays short, and each one links back to the fix or the stage it depends on.

Will a faster internet plan shorten the delay?

Usually not. Shot data travels over your local network or a direct link, and internet speed mostly affects downloads, online play and cloud features. A steadier local connection, such as a closer router or a wired link where your unit supports it, is more likely to help.

Why is the wait longer in third-party software than in the maker's app?

Usually because of extra steps. A connector app passes data from the launch monitor to the course software, and course software often renders heavier scenes and camera animations than the maker's range app. Update the connector, adjust camera and replay settings, and check that the PC meets the software's recommended spec.

Is the pause before the next ball the same as shot delay?

No. Shot delay is the time from impact to the ball appearing in flight on screen. Ready time is how long until the unit can read the next shot, and it depends on the unit and the software flow. Both shape how a session feels, so time them separately.

Does a 120 Hz projector make the ball appear sooner?

Slightly. Frames arrive every 8.3 ms at 120 Hz instead of every 16.7 ms at 60 Hz, and many high-refresh modes have lower input lag. The gain is only a few milliseconds, though, and it does not touch the seconds of processing delay that most sessions feel.

Is an iPad slower than a PC for showing shots?

It depends on the iPad model and the software. Recent iPads run tablet versions well, while older ones can stutter. Run the phone timing test on your own setup and compare the result with the same shot on a PC. For more on tablet setups, see our guide to simulator software on iPads and tablets.
