This is just a friendly message to anyone using Ubuntu 25.04 with an Nvidia 4000 (eg: 4070, 4080, 4090) or 5000 (5080, 5090) series GPU that, if you are using the Nvidia 570 driver, wait till the official 570 is available in 25.04 before sending any errors because only the 570.133.07 as seen here https://www.nvidia.com/en-in/drivers/details/242284/ fixes a huge performance issue on games like Hogwarts Legacy or Cyberpunk, whereas the games when they have Frame Generation enabled instead of giving the game 2x more FPS it actually punishes the game as mentioned in https://forums.developer.nvidia.com/t/clocking-issues-in-some-games-with-rtx-5080/322364/34
The fix is only found in the 570.133.07 as it looks by others or by going back to 565 which also returns the same good FPS performance, but of course without the benefits by the 570.
So basically we need to wait (In my case, I need to wait for the Nvidia PPA to get updated).
In my case, I can confirm 50% impact on a 4090, 5090 and 4070 ti.
