I have a Zotac RTX 2070 Super AMP and when benchmarking on userbenchmark it says my GPU is underperforming, which I think it is in GTA V. People say userbenchmark isn't totally reliable so I benchmarked using Superposition Benchmark on High and compared to others and my score is quite lower. I set the power limit to 111% (highest). Afterburner says that the power limit is constantly on 1 (well 1 then 0 then 1 then 0 etc. switching every second or less). When benchmarking I saw on the OSD that the power limit hits 112% then tries to go back up but hits 112% then goes back down again. I get that the limit is 111% but my GPU seems to really want to go higher and that may be the problem.
On the other hand when I use the benchmark the GPU boost clocks to 1950Mhz (no oc) as it should but then the core clock slowly goes and the temp slowly goes up.
EDIT: I have sorta fixed the problem. I undervolted the card and the power limit is barely hit and the boost clock lowers much slower and much less this time. As I lowers much slower, sadly it still does and it's because of the temperature.
Turns out the Turing (RTX) cards lower the boost clock as the card goes above 65 degrees celcius, even though 65 is still stable.I took the side panel off and put the fans to max while using Superposition benchmark and the clock stayed at 2010Mhz until it hit 66 degrees then decreased to 1995Mhz. The temp maxed at 68 degrees so the clock didn't lower after that but with the fan speed not maxed as the temp goes the clock goes down (I assume due to increase in resistance like a thermistor) and caps at 75 degrees on superposition where the boost clock lowers to 1920Mhz from 2010Mhz.
Thanks for the help but I guess I'm going to either water cool the card and hope it stays below 65 degrees or (more likely) wait till RTX 3000 series is released, sell this card and purchase one of those and hopefully they will have fixed this issue.
