Well. After completeing about 30% of Rise of Tomb Raider it's safe to say for sure that it is the most taxing gpu game I own. It's harder on the computer than the witcher 3. Playing it low at 720 with pretty much everything off has yielded between about 20 and 45 fps. I know that's a big number jump but it really just depends on the environment. The game really should've added an option to turn off the weather because that's what really kills the gpu. When you're inside of a building and there's no weather it runs super smooth on low but outside you can feel the cpu hit. Right now the only thing I leave on is Occalsion and FXAA filtering which has given me a FPS average of 35. Hopefully updates will optimize the game more, making it run better.
