Use CryoUtilities. Without it, the game crashes the whole system after 40min of gameplay.

For reference, I'm level 93 as a bleed warlock, which is a fairly intense build visually that I played entirely on the deck. The game was dropping a lot of frames on endgame, even becoming unplayable after running for a while. To fix that, I locked the GPU clock to 1200mhz and used FSR 5. That solved ALL my fps problems and the game runs on a stable 40 even on endgame. It does drop to 30-35 in really heavy areas, but before the tinkering was dipping to 10fps, so that's a big improvement.

I strongly recommend the game. The pad controls are great and the integration with the trackpad is seamless, making navigating menus much better.
