Low FPS in game after changing monitor

[mrwakett]

Hey guys,
maybe you can help me out. I play WarCraft 3 and stream on OBS studio.

So far I played on a laptop with a 1080p monitor at 60hz and had 200 FPS in game.

I stream in 1080p with 60fps in OBS studio.

Now I bought a new 144hz 2K monitor and as soon as I use it as a main display AND have the second monitor for Twitch chat tracking, my in game frames drop to 40-50 FPS and its pretty unplayable. If I remove the second 1080p monitor, the frames go up to around 150FPS again on the new 2K monitor.

Now my question is, can I fix this with some settings? I played around with OBS, Monitor and ingame settings but cant get any high ingame FPS using both monitors.

Or is my laptop just to weak to handle it? Its a pretty good machine though with a AMD Ryzen 9 5900HS + NVIDIA GeForce RTX 3080



Thanks,
Chris

Sounds like the multi monitor different refresh rate issue (google it) where WDM is scaling down to your lowest refresh
(Though this would be 60 fps, not 40-50)

Saying that, this has been fixed for a while now with recent windows updates.
So firstly, is your windows up to date?

Alternatively, you can try a relatively simple fix

Next go to your nvidia control panel and click on adjust desktop size and resolution.
Set both your monitors to "Perform Scaling on" to your GPU and not the display which is the default.

If you watch twitch streams or youtube videos or basically anything to do with chrome then you need to do this step or you can skip it.

Go to your settings in chrome and click on advanced options at the bottom and [disable hardware acceleration]

Thanks! yes windows is up2date. I cant change the nvidia settings because its only showing me the 24" monitor which is connected via a USB c hub. The 27" main monitor is directly plugged in to the laptop and somehow doesnt show up in the nvidia control panel settings, strange.

Hi! What version is your nvidia driver? I had a similar experience where I used to have around 80-100FPS while having OBS on and streaming then it dropped significantly to around 20-40FPS after I changed from my 24" to 27" monitor.

After troubleshooting for a few days, it ultimately was because of the newest nvidia driver I installed (reflex was to install to latest driver when i got my new monitor). I was on v517.48 while using my 24" then updated to v522.25 and v526.47.

The latest versions ate up a significant amount of GPU % (it was in the average of high 80's - high 90's, sometimes hitting 100!!!).

When I rolled back to v517.48, it dropped to mid-20's. And I was able to get back my normal FPS of 80-100FPS.

Try checking what version of nvidia driver you have and the GPU% when you have your game and OBS on. Then try rolling back to v517.48 and check the numbers again. Hopefully, we had the same issue and that this way will help you. :)
