1080ti upgrade from 980ti = worse performance!

Recommended Posts

I recently installed a 1080ti in my system replacing a 980ti. I know with P3D that required deleting shaders etc. I didn't make any bechmark for the 980ti so cant make any objective comparison but it sure looks like the performance of XP11 took a hit with the upgrade. So are there some maintenance steps I should be taking with XP11 when changing the GPU in system?

did that but that raises another question that's probably not for this forum but anyway. When I used DDU to remove the nvidia driver and restarted, windows 10 reinstalled an old nvidia driver 318.XX or something like that. It installed 3d Vision and everything. (HATE WINDOWS 10). I looked for solution to stop W10 from installing drivers but it appears that all those solutions merely stop W10 from automatically updating drivers.

I ended up using the clean install option under advanced user in the Nvidia installer to remove the old drivers and just install GPU driver, Hi def audio, Physx and Gforce experience.

If anyone know a way to stop W10 from reinstalling its saved old Nvidia GPU drivers on restart after using DDU, I'd love to know 😀

I similarly had some instability with stutters and fps after upgrading gpus recently. I did a clean install of drivers and that didn't do it. After about a week or two I remembered to delete and let X-Plane rebuild the shaders, then confirm my Nvidia inspector settings and monitor resolution were back at what I used to have them at. That seemed to fix my problems

What about the DDU restart in safe mode option?

Already did it by the book. Problem is that when W10 restarts after nvidia drivers are removed in safemode. It automatically re installs old drivers that it has stored some where.

Really don't know what is going on here. Download NVIDIA drivers, opt for reinstall, done. Why would you even bother with DDU? What the hell is DDU? Been installing NVIDIA drivers via the standard method in Win 10 for years and never had an issue, it's rock solid.

Did you try disconnecting from the internet while running DDU.

I just when't through the DDU restart in safe mode, uninstall and restart routine and ended up withe the Microsoft basic display driver as expected.

Back in win98 days I recall having to use tool similar to DDU. Since win10, I haven't had the need to uninstall video drivers, just download and let the new nvidia driver do its thing (clean install always), haven't had any performance issues at all. Even when replaced 970 to the 1070, I just removed 970 from devices, turned pc off, installed new 1070 and that is it, worked fine with no performance or driver issues at all.

I guess each system is different.

When I upgraded my card to 1080Ti, I deleted my x plane perf file, and shaders, and all good
