Hello everyone,
I just built a new computer last week with an AMD Ryzen 77800X3D and a XFX Speedster MERC310 AMD Radeon RX 7900XT. I installed the newest drivers and tried to launch a game (cyberpunk 2077). It launched but very slowly and stuttering. I then realized that Windows 11 used the integrated GPU (AMD Radeon graphics), so I changed the settings to use the 7900 XT on high performances. Then I tried to launch the game, but it freezes on startup. Idem for another heavy game like the Hitman 3 demo, but not with an older one like Borderlands : The pre-sequel which I can play normally. After the freeze, it either crashes or I have to terminate it with the task manager. Then the GPU stays active (I have a glass panel, so I see the "XFX" light staying on), the game is still running in Steam (I have to click on "stop" but it stays in progress forever) and I have to restart the computer to use it plainly again.
I already updated the BIOS, unplug and plug again the GPU end of the power cable, unistall and reinstall the drivers with AMD cleanup utility. Seeing on this forum it could be an issue with the newer drivers, I tried using the ones in this post. As a result, I now only had the 7900 XT running, not the integrated one, and I successed in launching the Hitman 3 demo, but it was again very slow and stuttering and basically unplayable. I updated to the new ones from here and the issue persists.
Does anyone have a solution ? Is this a problem that AMD will soon repair or is there something I did wrong ? It is the first time I build a PC and use this kind of hardware.
Thanks, and sorry if I made grammar mistakes as English is not my native language/
