So first time to post on the forums but usually go here to read about the game since I am a big fan. So wiped my hard drive and installed Linux for the first time and downloaded POE 2 there, got it to run on Lutris and got 60fps performance. Problem is I was kinda new to the Linux environment and it crashed on me and had to install Ubuntu again. Now, I can run Deadfire but the performance was like significantly impacted now I only get 30-45 fps in Neketaka. Some help would be appreciated guys. I think my rig can handle it on 1080p 60fps got a i7-7700k and 980ti. 

Was it raining in Neketaka? This game is so poorly optimized it makes high end gear act like toasters. With your rig you should be getting 60fps tho.
