Popping in to give my 2 cents, as the person who hosted the stream and developed the tool.

TL;DR: The results in the stream were largely good, with 1 game having slight negatives and the other 2 games being better with CU2. Saying “it’s dead” is an extreme overreaction, especially considering I tested games that have historically benefitted very litte from CU2. The entire reason I chose those games is because I wanted to make sure that the “worst” ones would still not suffer, further testing with games that should actually benefit is necessary.

Here are the exact numbers, in the order I tested them:

Red Dead 2 got better performance with CU, even WITH the 200/1040 bug on the CU runs:

Default Preset had a substantially better minimum, and was much smoother:

Without CU:
Min - 22.0081
Max - 63.9321
Average - 49.8511

With CU + 1GB VRAM:
Min - 28.6349
Max - 63.2811
Average - 50.6368

“Prefer Quality” Preset was slightly better across the board:

Without CU:
Min - 19.3353
Max - 59.8151
Average - 46.3316

With CU + 1GB VRAM:

Min - 21.7967
Max - 59.4665
Average - 47.0571

Cyberpunk 2077 had minor losses, but it seems that it is at least partially the fault of having less RAM with 4GB of VRAM, needs more testing:

Steam Deck Preset lost about 1FPS:

Without CU:
48.61

With CU + 4GB VRAM:
47.88

High Preset also lost about 1 FPS:

Without CU:
43.87

With CU + 4GB VRAM:
42.88

Horizon Zero Dawn had gains nearly across the board:
Original Preset was within margin of error:

Without CU:
9/50/97

With CU + 4GB VRAM:
8/51/99

Ultimate Preset had gains in both highs and lows:

Without CU:
9/36/70

With CU + 4GB VRAM:
12/36/76
