    Tested this only with 1 game on my end, and FPS has increased by ~1-2 in accordance with the in-game benchmark. Re-tested multiple times.

    However, the main benefit to me (maybe bias + placebo) is that indeed it seems the overall latency is better, so gameplay on sub 60 fps feels "smoother".

    This still doesn't even show up for me. When I go to graphics settings its just not there. I'm using 451.58 and the latest windows update from May 26th.

    Neat little story, I’ve been running the 451.48 driver with HAGS enabled without many problems. Framerate including 0.1% and 0.01% seem nearly unchanged, perhaps slightly better. Especially input lag seems affected.

    As Microsoft themselves also acknowledge, it’s all in a very fresh phase and certainly seems a nice foundation to build on, wouldn’t surprise me if AMD and Nvidia can extract extra performance over time. Can’t wait what is around the corner with 2009 or 2104(?) performance improvements big or small are always welcome!

    Same thing my 2080Ti system is telling me. 5700XT system upgraded with no issues after installing the newest video drivers.

    I don't know but since I enabled it, my desktop is running like if it was without any vsync, there's the framebuffer split at about 25% from the top of the screen

    I thought Nvidia did away with Hardware Scheduling, doing it in software via drivers with a fixed queue length? Or has that changed with Turing?

    @Astyanax You're usually very knowledgeable with this kind of thing, can you offer any insight?

    hardware scheduling whether it be full featured or software interactive is required for quite a bit of future DX12 feature sets to come.

    I tested several games on a desktop machine. I do not find a difference with the exact same settings on any game I tested with HAGS On/Off

    The link posted by CPC_RedDawn with adored TV in gears 5 he was using a laptop with large difference. I just tested on desktop Gears 5 with zero difference.

    These drivers change enough that there are some compatibility issues.

    I have been using VirtualBox for encapsulation for several years and both host and guest were upgraded to 20H1 without issue, the host runs a 2060.

    Everything was fine until I installed the new Nvidia drivers. After that it became impossible to enable 3D acceleration on the guest. Doing so locks up the VM so badly that forcing it to shut down causes VirtualBox to crash.

    This is as much nvidia's fault as it is Oracles, the maroons at oracle are rejecting the driver based on a single certificate not having a vertification chain, ignoring that the driver is fully sha 256 WHQL signed and that includes a full verification chain.

    I'm going to open a custhelp issue to nail down the last few files that need the nvidia sha1 updated to a sha 256.
