[SOLVED] Asrock RX 6900 XT Phantom Gaming gives very poor performance in older games ?

[bjoxu]

Hello,
my friend just bought brand new Asrock RX 6900 XT Phantom Gaming and have big issues with FPS spikes, mostly in older games thats not heavy GPU demanding. For example he have 40fps in Wolrd of Warcraft no matter game settings. More demanding games like Elex, Cyberpung on ultra in 1440p have at least 100fps. Its noteworth that GPU Frequency is spiking from 200 to 2000Mhz during wow gameplay.

GPU: Asrock RX 6900 XT Phantom Gaming
CPU: Ryzen 7 2700 -> Ryzen 9 5900X comming
MOBO: X570 chipset, dont know exact model
PSU: 750W

Any ideas what could be wrong. we tried to force GPU to 1000+ minimal frequency in Radeon software but it seems that doesn't affect GPU behavior. Any ideas what could be wrong? We went through a lot of thread and news that was reporting the same issue but coun't find any solution. is this still ongoing issue?

Try to determine the Motherboard model by download and installing CPUZ, open it and go to Mainboard tab, then post a screenshot here.

Try These:

• Uninstall GPU Driver Using DDU and Download your motherboard bios, extract it and copy the file/folder to your flashdisk (plug the flashdisk into the back of your motherboard)
• Uninstall all the processors in device manager like this, and reboot to bios:

• Update motherboard bios to the latest
• Install the latest AMD Chipset driver, reboot, and open power plans in settings, and choose AMD Ryzen Balanced
• Install the latest Radeon Driver, then try to game on again.

Do this all offline, download the necessary apps first before disconnecting from internet.
