anyone tried the Hardware-accelerated GPU Scheduling setting? I've turned it on (requires latest build of windows 10 2004 and these drivers)
 
I haven't run it through any tests yet to see if there is something different, but I'll let you know if I notice anything.

I haven't tested it to see if there are FPS gains, but I did play one game with HAGS enabled so far.  I wanted to see if there were any differences using all the same settings (game & nvcpl) while playing.  The game I tested with was AC Odessey.  With all settings being equal from the last WHQL driver to this one using HAGS, I saw more consistent Frame Times.  Almost a flat line.  I also saw that where my max GPU usage was 97/98% with the last driver (pre HAGS) to maintain a steady 75 FPS, running this new driver with HAGS enabled I had a max GPU usage of 86% to achieve the same.  That also lowered my max GPU temp ~ 2- 3C because of the lower usage to maintain the same frames.
 
So far from my little bit of testing, HAGS look pretty promising.  No complaints.

look forward to more info & testing from people on that new feature.... 
 Any performance boosts would be nice ....

Well the youtube video shows 5c more with it activated.. Won't try that in summer I guess !

I enabled it and ran benchmark in RDR2.  Before...in fps  1440P
 
min  25
max  122
Avg  50
 
After
 
min  32
max  66
Avg  56
 
Part of the problem I have with the benchmark in the game...the transition screens count toward the max.  Example...between scenes...the black screen will show 250 fps.

Regarding HAGs, my testing in Warzones and Battlefield with this driver on build 19042 (Slow ring) has shown a boost in peak FPS, little to no change in average FPS, and a massive improvement in FPS stability and jitter.
 
I believe HAGs + 45x drivers may have finally fixed a major cause of stuttering and jitter in DX11 and DX12 games, and is probably related to the so-called "standby memory bug" that has plagued Windows for ages. My guess is that VRAM allocations should never have gone through Windows' wonky and unperformant memory caching mechanisms. So this "feature" is basically the correct implementation that should have been in effect since Windows 10 1607. Obviously, this is just my opinion so take with a grain of salt! Regardless, HAGs is looking good for an essentially no-cost FPS stability improvement in modern games. Based on the Nvidia forums it has caused some issues in older titles so depending on what you play it may make sense to keep off for now.

One of the touted gains is video playback. I've noticed that with Folding@home running in the background I much less frequently see pixelation issues when alt-tabbing to videos playing in VLC. I can bounce between chrome or apps to the video and it won't have pixelation corruption. Before hardware scheduling it was a regular occurance if I was Folding in the background. The touted latency reductions appear to have very real benefits. 

 
Thanks.    

I guess I can put this here , pertains to initial tests using the new feature.
** basically almost nothing **

At present, across five tested games using multiple APIs, on average (looking at all nine or ten tests), the change in performance is basically nothing. The 9900K with RTX 2080 Ti performance is 0.03% slower, and the GTX 1050 with the 9900K performed 0.73% slower. The 3900X with RTX 2080 Ti did benefit, but only to the tune of 0.06%. In other words, the one or two cases where performance did improve are cancelled out by performance losses in other games

This sounds promising. This problem has been a big issue for quite some time now! Funny how neither Nvidia nor Microsoft ever acknowledge an issue that caused so many performance issues. I've had to run a task to wipe standby memory every 5 minutes for years now on ALL of my computers.
