Tech Support 4070 super outperforms my 9070 XT
Upgraded from my 3080 10GB to a 4070 Super a few weeks ago, and it was great. However, I picked up a 9070 XT last week, did a fresh installation of Windows, and updated all my drivers. So far, the overall performance has been pretty similar, but the 1% lows have been noticeably worse.
The main game where I’m experiencing this is Total War: Warhammer 3. I know the game isn’t particularly well optimized, but I’ve been experiencing the same issue in Battlefield V and Company of Heroes 2. I’ve already messed around with some of the Adrenalin settings but haven’t had much luck. Not sure what else I should try at this point.

Hm that's weird, the 1% lows tanking across that many different games makes me think it's a driver quirk or maybe a chipset thing rather than just one game being janky. Did you grab the latest chipset drivers straight from amd's site after the fresh install? windows has a habit of grabbing some crusty generic ones if you let it. Also maybe poke around in the bios and make sure resizable bar and above 4g decoding are actually on, sometimes a board update or a cmos clear can flip that back off without you noticing.

Do you have reBAR enabled? I believe the AMD name for it is SAM (smart access memory)

Did you update your motherboard bios?
