Still scratching my head on my pc. Build a new pc about a month ago. Play on my pc one night at 340fps on siege. Turn my pc back on the next day and it's down to 110fps. Turned off windows game mode and got it back to 280fps. My true benchmark game is rainbow six siege. Rainbow six has an auto detect on it and when I click it, it now goes to all medium settings which makes no sense as geforce says optimum is ultra everything. Every game I own is down about 60 fps but when I run benchmarks it says my computer is amazing. So why are games not performing the way they did. No updates done to the computer at all.
