So i upgraded my 1060 3gb and bought a gigabyte rtx 2070 super last week, at first it performed very well on all the games i tried (like Apex legends, pubg, overwatch, witcher, etc..), after a week of use it started to get lower performance. On the game its performing specially really bad is on PUBG, first week playing pubg i had graphic settings on ultra at 1080p and had +140 fps average on any map, now im gettiong 50-70 fps most of the times, doesnt even get to 90. What the hell?? Ive noticed a little worse performance on other games, but not very noticable as they hit +100 fps. Now, i know that my CPU listed below (ryzen 5 1600) might be causing a bottleneck, but the thing is, wouldnt it be bottlenecked from the beginning? Because the first days i had a lot more performance and suddenly after a week it dropped a lot around 30-40fps on all games, but a lot more fps drop on PUBG. Even when i had the 1060 3gb, it performed a lot better in pubg than my current rtx 2070S, it is really unplayable.
My RIG:
ryzen 5 1600
2x8 2400mhz RAM corsair vengeance cl16
gigabyte rtx 2070 super
