Hi there,Re installed windows, deleted all mouse files? So you didn't do a CLEAN install? Is Windows fully up to date? Why are you using a 1200Watt PSU? Water cooled? LOLZ, I assume its the CPU(assuming you do have one) cause you don't say what you are using here.
I've reinstalled Windows (clean) and not just Windows 10, I've tried 7 also. I've tried a lower Watt PSU, the issue is still there and the reason I use a 1200 is because my friend gave it to me. Yes, the CPU is water cooled.
The problem is still very much there. When I look at other videos of people playing games on inferior setups they have buttery smooth gameplay whereas I have small very subtle-micro stuttering and slight input lag. I get on with it but it has cost me, I now accept I can't compete at the level I want because of it. Better than nothing I suppose but when you spent lots of money on upgrading and moving forward with newer technology you expect improvements not steps backward
If anyone has any suggestions please let me know, thanks.
