I recently updated my Windows 10 to 1511 and updated my graphics drivers as well. I updated to 15.11 first and I had some performance issues which prompted me to update to 16.1, I've been attempting to find a solution for almost 3 days now, and I simply haven't been able to.
Radeon Software Version - 16.1
Radeon Software Edition - Crimson
Graphics Chipset - AMD Radeon R9 200 Series (R9 280X)
Memory Size - 3072 MB
Memory Type - GDDR5
Core Clock - 1072 MHz
Windows Version - Windows 10
System Memory - 8 GB
CPU Type - Intel(R) Core(TM) i3-4150 CPU @ 3.50GHz
I can't play any typically low requirement games with even average frames, CS:GO I get a maximum of 30 frames (frequent drops to below 10 when shooting), Minecraft I get sub 20 FPS, League of Legends feels stuttery, not sure what the frames were, but they were definitely worse than normal. For comparison, I use to get 80-100 on the same settings on Minecraft and 144+ FPS on CS:GO with higher settings (lowered it to see if it would change anything). Sometimes even full-screen video stutters (sound as well) while being completely buffered.
Things I've tried:
Fresh install of the driver (completely removing/rebooting into safe mode etc./reinstalling driver)
Tried downgrading to 15.11
Made sure my DVI-D cables were tight (mobo/gpu to monitors)
Reinstalled Windows 10
Note: My GPU Load value fluctuates from like 0% to 35%, goes back to 0% quite a lot.
