Symptoms

At the patch where the Warframe 1999 demo released I started experiencing frame rate issues in Warframe but only after about 30-40 minutes of playing. Up to then I get solid 60 frames per second then suddenly it becomes a laggy mess. I have checked for back ground processes starting or something similar but a simple quit and restart of Warframe resolves the issue. All game modes affect solo or online. I have tried Proton Experimental and 9.0-3. Changing graphics settings to minimum does not resolve the issue either. Verified PC is not overheating, max core temp was 55 so well below anything I would worry about, immediate restart also gives another 30-40 minutes of play before issues start again so 99% sure its not heat related. Uninstalled and reinstalled Warframe completely. Let shaders precompile in steam, skip shaders, disable shaders, all the same result. DX11 and DX12 same result.

Issues are not present when running the game in windows.

Reproduction

Start game, begin playing after about 30-40 minutes begin experiencing major frame rate instability resulting in very poor game play
