Rtx 3080 ryzen 7 3700x bad fps

Those are really poor frame rates for your hardware, I’m surprised, although a 3700x isn’t fantastic (I’m only on a 3800X myself) it should do better. In energy options, if it’s there make sure you have AMD high performance mode enabled rather than just the Windows one and I presume you have an XMP ram profile in bios enabled. Kill anything running in the background including Dragon centre, GForce experience etc. as you could use the spare overhead and finally this is the best tuning advice I’ve found on the forum, take particular note of those settings that are CPU limiting.
