Games on Steam Lagging and Freezing a Lot

When I launch GOW 2018 via Steam, the game starts lagging A LOT and even reaches a point where it simply crashes. I have an RX 6600 and a Ryzen 5 4600G, and I was able to run this game at Ultra smoothly on Fedora.

By the way, I noticed that the game only freezes when it's set to the Ultra or High preset. When I lower it to the Original or Low preset, I can play, but there are still some stutters.
