holy, 45fps? Obviously i didn't mention gear, professional setup makes your game work properly and smooth, but i can't really imagine playing with low sens on 45fps, especially when you don't have t1 mouse with a large mousepad. I'm angry whenever my fps drop under 300, so i understand this then. However, if you're going to upgrade your pc gear sometime, it actually does make sense trying to lower your sensitivity. Good luck, it reminds me of playing csgo like 4-5 years ago on low-budget setup when i didn't even care about sensitivity etc and was playing on default settings. Of course it's just personal preferences, but when you get stable 300fps you clearly feel that difference at smoothness between pixel and clean aim.
