HELP: Lag Spikes in borderless/windowed and terrible screen tearing in fullscreen
So I have been playing in borderless and windowed mode since the release of the game and I have over a hundred hours already in which I was having no issues. Yesterday when I opened the game and starting playing I immediately was getting random fps drops no matter where I am in the game, menu or in game. It makes it unplayable. I have tested lots of stuff and can not find a solution or understand why this is happening... The fps drops stop when I turn on vsync, however I can't play on vsync because of the input lag, so that isn't an option. Something else that stops the lag spikes is going into fullscreen. The issue with this is that it causes extreme screen tearing.
Want to mention that the fps counter I have in game stays at 60 even when it clearly is not 60.
I do not know what to do. I play at a high level, so I can't afford to play with input lag, so vsync is not an option unless there's a way to remove the input lag. I need to fix the random lag when in borderless/windowed or I need to fix the screen tearing when in fullscreen.
I have had no windows updates or driver updates, so this isn't the problem.
My monitor is also 60hz, so I don't see why vsync is causing screen tearing.
I also completely factory reset my computer today because I am desperate for something to fix it. Well, that didn't change a thing. No change in the fps drops or screen tearing. So I am very confused and need help (I'm need to fix this:()
I also have no issues in any other games. I tested 4 different games today, including trials fusion.
Also want to mention that my cpu/gpu/ram usage is normal, not maxing out or anything.
If somebody can fix this for me I will literally send you $150 paypal (no joke)
