FPS too low

I recently tried the new Reshade for a new game but I'm experiencing some issues with FPS. The game I'm using it on is Modern Warfare and when I use it I go from 160 FPS to 80-90 even with all effects off in Reshade, just having Reshade's dxgi file in my game causes this issue. I read Reshade is mostly GPU related, is a GTX 1080 not good enough for Reshade?

No, without any shader active ReShade should have no impact on the game's performance. However, I'm at a loss at what could cause this, maybe someone on the Discord channel knows more... discord.gg/PrwndfH
