Since I purchased the Sapphire reference rx5700xtcard on August 29th from Amazon, i have been suffering from the low-performance issue.
I am using 19.9.1 driver with a clean and fresh( installed this afternoon) windows 10 1903. The average frame rate per second in Rainbow Six siege is 122 under high setting and 1080p. My previous gtx1060 from Zotac have the same frame rate. I also noticed that my Time Spy score from 3DMark is only 4200, half of the benchmark score i can find online.
In addition, I cannot read the frequency and temperature of my card through any software. I've tried Msi Afterburner, Wattman and 3Dmark.
What should I do to boost the performance?
