I have a 7700k i7 with a 1080ti OC on Windows 10 I have dvr and the new gaming thing creator update added disable or uninstalled, no avast etc.... When I even open a game like paladins I go from 250 fps down to 110 sometimes down to 60... This isn't recording or anything just with OBS open. It's a massive chunk in other games it been taking over 60-70 fps away.

I've seen some other posts about this on the forums but when will this be addressed?

No real skipping of frames as OBS for some reason is just taking way more frames than usual. Usually it's around 20 or so.. never 60-100 frames. Brand new computer all the drivers are up to date. Is it this windows 10 creator update that is causing the issues and the way OBS operates that is causing this FPS loss?

yeah there are a ton of posts on OBS FPS drops and it's just from the application being open. This is a brand new computer fresh drivers I've uninstalled the drivers with DDU a few times now to no avail.

Bump.. the only solution i found was on reddit to go to "Disable Fullscreen Optimization" in the compatibility tab of each games exe that is having the problem... I've seen people report this issue since March and it only effects OBS and not Xsplit this needs to be fixed.

Nothing was changed regarding game capture, other then the 32bit dx9 capture performance fix.
Running your game at 250+ fps is bound to use all the GPU resources, leaving nothing for OBS and if Windows also decides to interfere with things, then I can understand why it drops so heavily. Enable vsync to keep the fps lower, so OBS and the game don't have to compete over the GPU resources.

I can take pictures of the gpu and cpu not even going above 50%. I'm not new to this Osiris, I'm a partnered streamer who does this full time. Something happened to how windows and obs work together since Xsplit does not take such a hit on fps. There are a ton of posts stating this just having OBS open will tank the fps.

I found posts/videos about this exact issue with no actual fix. The only thing that seemed to help to make it at least playable at roughly 144fps in Paladins was the disable fullscreen optimization that was added in the new creator update.

If this is the Discord interaction we've seen, it'd be useful information to know if disabling the Discord overlay is enough to resolve, but if that doesn't fix the problem, definitely try it with Discord shut down entirely.

Hey so tested a few different scenarios. Discord on or off had no impact ( made sure the exe was not lingering). Never turned on overlay I turned it on and off just incase.

I have stableish FPS now but the only way to achieve that is by disabling fullscreen optimization in the exe file under compatibility. So not sure I know windows did something where they changed how fullscreen works as you guys said in the win10 sticky.

But to get 144 stablish fps I have to tell the game to run at roughtly 300-350 fps because the hit is so great even with obs. But the workaround with the disabled fullscreen optimization is a temp fix for now. Hope you guys can figure out the root cause I'm assuming it's on windows side.
