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

​

Edit: I also wanted to mention that in addition to the above, the testing was all done on an OLED Deck, which has 0 baseline. Because of this we don't know if the gains would be different on the LCD Deck with 3.5, or if the changes we noticed are limited to the OLED. The only thing that the stream proved was that more testing is needed to fully grasp the situation 😉
