Massive CPU Bottleneck on 13th Gen Intel after GPU upgrade
So, I recently bought an RX 7800 XT (upgraded from an RX 6700 XT) and I've been having issues with the game not going past my old GPU's usual frame rates. I usually test my frames in Operation Firestorm, and in certain areas I get dips all the way down to 150 FPS in the same spots where my old 6700 XT would do the same... Except that I got an i7-13700K CPU, and there is pretty much no conceivable way that this GPU would get bottlenecked by it. In those locations there's a discrepancy between CPU and GPU FPS of over a hundred frames, and I don't think that's even remotely normal.
I've tried clearing CMOS and only using XMP and nothing else, but that results in my CPU overheating. I've tried user.cfgs, I've tried undervolting, I've tried custom profsave_profiles, passed DDU and reinstalled various different drivers at least five times, nothing seems to work. My GPU is just stuck in the same exact frame rate my old GPU had. Hell, I actually reinstalled Windows due to an unrelated issue and it still didn't fix it. I've also tried to do a full reinstall of BF6 by using Revo Uninstaller and deleting anything Battlefield related from my computer entirely, and it still didn't fix it.
Is this game just cooked for me eternally? I don't want to have to go to a 14900K to be able to play, but knowing DICE even that wouldn't fix it.
Ok, so I might have inavertedly fixed it. I clean installed Adrenalin 26.9.1, after passing AMD Cleanup Utility on the PC on Safe Mode, and tried to boot up the game, but I still had the same issues with frame rates. So I went on the BIOS, and removed the undervolt on my CPU while keeping all of the other settings, and deleted the Battlefield folder from %localappdata%, and in Adrenalin I reset the shaders at the same time and let them rebuild. Game no longer dips below 175 fps, even in busy moments, and my averages are at around 185-210 FPS. So, if any of you are having issues, try removing your undervolt or overclock if you have it. I am using the Intel Max Performance profile, too, so it's technically overclocked, but it's within Intel spec so it doesn't make the game behave weirdly. My GPU FPS did go down from around 260 in the same spot to 220, but my CPU FPS went up (on the same location that I was getting around 145 FPS I am now getting 182), so I'm happy with the results.
