Hi everyone, I was able to get my GPU up and running on my Windows 10 guest machine thanks to @gnif 's help.
The performance is great and I’m not having issues most of the time but when I try to play Remnant 2 random crashes like
Out of video memory trying to allocate a texture which I know it’s not true because I’m using RX 7800XT 16GB.
and AMDRSServ.exe: Application Error. The instruction at referenced memory at 0x000000. The memory cannot be read
Looking at the Windows event logger I noticed that I keep getting this exception code 0xc0000005.
I have test two games, Remnant 2 and Helldivers 2.
I know it’s an Access Violation exception and I’m suspecting that it could be the RAM.
Is it because I don’t have HugePages setup?
Here is my XML
