2080ti performance drop

[SuitUpGamer]

Hey there. I am having a bit of a problem. My 2080ti has dropped drastically in performance. In some games not even hitting 60fps any more. It used to run fine for a couple of months, and then suddenly, without any changes in the system i get performance drops. I have tried a full reinstall of drivers, but nothing changed, full reinstall of windows, but same result. i used to oc my card, but can not hit same lv of oc any more without crashing, i get very close to same oc though. The card is not overheating and powerdraw jumps between 90-100 in benchmarks. 
I have tried benchmarking in timespy.

 

Result before performance drop:

Result after performance drop:

Slight differences in OC but i can not imagine that small numbers like that have such a huge impact on performance..

 

I started noticing performance drops in BL3 where i would drop all the way down to 45fps in some areas. Changing in game settings only affected fps with 3-5fps. Same with other games.

Temperatures and clock speed? Especially check the GPU clock speed whether it gets stuck at 1350MHz

[SuitUpGamer]

Temperature between 75-80 on air. Timespy and MSI afterburner stating clockspeeds close to 2000mhz

Maybe important to know, not sure, but gpu is moumtet on a vertical riser card from lian li. Do those mounts create problems in the long run? I will try mounting the gpu in a more traditional manner and see if the problem reoccurs

Not normally no. However moving them too close to the side panel glass can starve them of air. Which will lower the boost speed. My founders 2080ti stays around low 70c . But I do have 3 intake fans directly below it forcing in cool fresh air.

 

From your 2 results, the only difference I can see is the max turbo boost. But its only like 100mhz. Which wouldn't account for much. When you formatted did you install the same driver version ae before? Maybe try rolling back to a version you knew was at its peak.

I also doubt that 100mhz in boosts peed can affect performance that much. I have not yet tried with an older driver. The option to rollback driver is greyed out. Where can I download older driver versions?
