It's 566.36 drivers, installed with the Nvidia App (originally) and now tested with a clean install (Display Driver Uninstaller, plus I tested some other GPUs in the interim) and this time I selected to only install the drivers. You get that option with the drivers, just like with GFE where you could opt out of installing it. I never trust Windows Update to provide current drivers for GPUs.Just making sure:
Is this Nvidia app vs GFE or Nvidia vs no software at all? If the latter, are you relying on Windows for the drivers?
Took some reworking of my scripts to easily extract the data, but...Out of curiosity is the CPU load different with it installed vs uninstalled?
The rest of the physical numbers (not FPS) seem like they would be within a margin of error.
Avg. CPU load:
Without NV App: 28.7%
With NV App: 29.6%
Avg. CPU power:
Without NV App: 57.0W
With NV App: 57.3W
So still a small enough delta that I don't think that's it. Probably just some code where it's causing stalls in the GPU or drivers.
