I have an EVGA RTX 2080 and I decided to overclock it today. After running multiple tests on the Heaven Benchmark thing, I was able to get +1000 MHz and +130MHz on EVGA Precision X. I also ran a couple pre made benchmarks on some games that I have such as WWZ. However, when I was playing fortnite the core clock stayed at 1515 MHz which I assume is the base clock. It boosted up to like 2040 MHz only when I maxed out everything to epic, but I don't play on those settings. Why is this?
