GPU may get stuck in P0 state after exiting certain games 
I have an RTX3070. When I tried the 526.47 and 526.61 drivers I had numerous DWM and DWMDLL failures (3 or 4 a day) and had to revert back to 522.25 to resolve the problem as several others on the NVIDIA boards noted. I didn’t notice whether the GPU usage was high before, but it looks like since this is an open issue it may not work for me. Thank goodness for DDU!
I think the best thing would be to try it and make a comparison for yourself. What works today might not work tomorrow. Software continues to change/develop over time, performance results will vary, improve and get worse. Results will differ across users. At the end-of-the-day you will have to make a decision as to whether you keep GFE or not.
Yeah, no harm in trying, its just hard as there is no way to get a reference FPS - every time you load a scene or return from menus, the FPS seems different even when no changes are made
i guess, if the difference is not immediately visible then its not worth worrying about. I just downloaded the new driver and left the GEF off, plus did a clean install so it reset my NVCP options as well. WIll see how it flies tomorrow, no doubt after the download…
Working fine on my system so far (Ryzen 3700X with RTX 2070 Super), not noticed any performance differences from the previous version.
One thing that is slightly different is that my Geforce freestyle filters need to be set differently than any previous versions to acheive the same visuals.
Not sure if that’s releated to the HDR 10 + support that is mentioned in the driver update notes, but I doubt it as my monitor only supports HDR10.
