it is possible to render obs on other GPU ?

it is possible to render obs on other GPU ?

Possible? yes.
Worth it in your setup? no.

The sheer amount of performance loss you introduce by trying to do so makes it not worth it.

Post your FULL OBS log

In any scene where you have display capture and game capture together, remove one of them.
Remove ALL game capture sources from ALL scenes, except for ONE game capture source. Set that source up to use hotkey based selection.

I tried to make clear scenes with unique game capture source

i found dependence if source using filters

i realize that my GPU cant handle 60fps in obs with AAA games, i need to restrict frames in game or change obs to 30 fps capture, or use clear scene with 1 source without any other media source and filters
