I have a Toshiba Satellite M50D-A-118 running Windows 10 and I just updated my AMD drivers with the AutoDetection Tool. Everything went fine during the installation but now that I rebooted my system like it told me to do, literally I just have to move my mouse for my whole PC to lag... I can't figure out what the problem is, I've tried to run some programs related to the mouse in compatibility mode with other windows versions, checked device manager to see if anything needed and update, but not only this, the strangest part is that in Task Manager, even when I move my mouse and the PC lags, it says the CPU performance only spikes up around 1% - 4%.
I really need help since this is making my PC really hard to use and I've played CS:GO, which I play in a different resolution and on fullscreen mode (one of those might have stopped the issue) but when I open the steam overlay with SHIFT+TAB the issue still happens there and when I open the game console aswell. Nothing else on the game lags.. I've also tried using the trackpad but the same thing happens, and my keyboard also seems a bit laggy. Also, I use an external display and have tried to plug it out, update its drivers (which were already updated) but everything remained the same.
