I checked a few games myself before and after updating to these drivers and saw no improvement on my 3070@1440.
Division 2 DX12 showed <1% difference gain is FPS, though the CPU graph was slightly smoother.
Other DX11(Hunt, Steep) and Vulkan(Rage 2, WWZ) games had no gains.
I didn't change any settings or test other resolutions so YMMV.
I've not had any stability issues with these 522.25 drivers.
Other sources are claiming the performance gains are from "shader compilation optimizations, improved Resizable BAR, and less CPU overhead".
Supposedly, these gains were seen on a 3090:
Assassin’s Creed Valhalla: up to 24%
Battlefield 2042: up to 7%
Borderlands 3: Up to 8%
Call of Duty: Vanguard: up to 12%
Control: up to 6%
Cyberpunk 2077: up to 20%
F1Ⓡ 22: up to 17%
Far Cry 6: up to 5%
Forza Horizon 5: up to 8%
Horizon Zero Dawn: Complete Edition: up to 8%
Red Dead Redemption 2: up to 7%
Shadow of the Tomb Raider: up to 5%
Tom Clancy’s The Division 2: up to 5%
Watch Dogs: Legion: up to 9%
They claim higher end cards gain more, with the 3060 only gaining up to 7% on AC: Valhalla
Seems like more gains on games that use resizable BAR, but IDK...
I was hoping to see something, but on my rig, on my settings, on my games, I got nothing...
