Ok, so first off, I have my FPS set. It's at 144, as is my refresh mate of my monitor.
I get around 130-140 in game, on high settings, which is fine. The issue is the main menu, where something is going on, like it's trying to constantly render in 1 billion poly's at 16k. The second I join a server, gpu usage drops back down to 50-70%.
AMD's limiting doesn't do anything, as it's not even reaching these caps, it break about 65FPS at the main menu and stresses the hell out of the card.
Settings do not matter at all, low high, ultra, downscaling to 1080, nothing.
I have tried all these solution myself and to no avail, which is why I believe there is some issue between the latest update and AMD drivers, specifically for my card, as I know two people with pretty much identical rigs, and the same GPU's and this is happening.
