Ping spikes

Ping spikes

james 5

Hi

I’ve been experiencing an issue on Roblox where, in most games, if my FPS is uncapped and running anywhere from around 500 to 1,200, my ping will suddenly spike and keep going up reaching as high as 21,000 before eventually dropping back down to around 30. This usually happens when I reload or move around in the game.

When I cap my FPS at 240 or 360, the issue doesn’t seem to occur. It also doesn’t happen in any other games, and my internet connection is stable when tested in Command Prompt, my ping consistently stays around 5–6 ms.

Does anyone know what might be causing this or how to fix it?

Hello james, welcome to Microsoft Q&A.

It sounds like the ping spikes are happening because Roblox is running at extremely high frame rates when uncapped. When FPS goes up to 500–1,200, the game engine can use a lot of CPU and GPU resources, which may interfere with network tasks and cause latency spikes. This is why your ping jumps to very high numbers and then drops back down.

Roblox is not designed to run at those frame rates, and most games work best at 60–240 FPS. Other games may handle resource allocation differently, which explains why you only see this issue in Roblox.

Here are a few things you can try:

Cap your FPS Keep the FPS limit at 240 or 360. This is the simplest and most effective fix.
Enable V-Sync or set a frame rate cap in your GPU settings If you use NVIDIA or AMD, you can set a global or per-game FPS limit.
Update your graphics drivers and Roblox client Outdated drivers or game versions can cause performance issues.
Close background programs Make sure nothing else is using a lot of CPU while you play.
Lower graphics settings in Roblox This can reduce the load on your system and help keep things stable.

Hello Thomas, thank you for the response. I've honestly tried I think all of these things but no luck so far. The thing is it sometimes doesn't happen in some games and all of my friends run around the same framerate and don't experience this issue so I'm just so confused as to why its happening to me only.

I'm sorry to hear that. It could come down to hardware differences. Small variations in CPU or GPU architecture can change how the system handles extreme frame rates. Checking temps and usage during gameplay might reveal if that’s happening.

What should I use to look for that and what exactly do I look for?

You can use Task Manager or a tool like MSI Afterburner or HWMonitor to check usage and temps.

Here’s what to look for:

CPU and GPU usage: If either is hitting close to 100% while FPS is uncapped, that’s a sign the system is maxed out.

Temperatures: If CPU or GPU temps are very high (usually above 85°C), throttling can kick in and cause instability.

Clock speeds: If you see sudden drops in clock speeds during spikes, that’s thermal throttling.

Start with Task Manager (Ctrl + Shift + Esc) under the Performance tab for a quick check. If you want more detail, MSI Afterburner or HWMonitor will give you temps and clocks in real time.

I Used HWMonitor to check and im not entirely sure whats normal but maybe you can tell me these 3 screenshots are from when the fps was uncapped/set to a limit of 9999 also just to add this ping problem it doesnt really happen in every game from my understanding and in the games i tested it in the most they are very similar it mainly happens when i start shooting constantly and reloading. The Dark screenshots are from when it was capped at a cap of 420 that seems to be the highest cap i can use without the ping issue happening.

Your temps and usage look normal, so it’s not overheating or maxed-out hardware. The spikes are likely caused by Roblox struggling with extremely high FPS during heavy actions like shooting and reloading. Since capping at 420 fixes it, the simplest solution is to keep the FPS limit there. Roblox isn’t optimized for thousands of frames per second, so running uncapped can create resource and network timing issues.

Okay well thank you for your help anyway then im still a bit confused how many people i know are able to run in the hundreds if not thousands 1 person i know running over 1.3k in the same game i play but they dont seem to have the issue but I guess it feels the same to play on 420 as it does anything higher so it should be fine.
