Premiere pro 14.8.0

[DjAligator14]

I have problems with premiere it's very laggy and uses 100% from gpu that's when i try to play a clip in it, in timeline or source. 

This happen with some updates, i had a gpu gtx 980 now i have 3090 with amd 5950x and i still have this problem but now it's worse.

If that doesn't work, try Preferences > Audio Hardware and set Input to None.

If that doesn’t work, try updating or rolling back your graphics driver directly from the video card manufacturer’s site. If NVIDIA, do a clean install of the latest Studio Driver (NOT the Game Driver).

If that doesn't work, try creating a new project and import the old one into it.
