Should I change memory mapping for ADATA 4GB DDR4 shared VRAM?
I actually got it to run! Using only 4GB of RAM is basically a suicide mission for modern AAA titles, but the extreme optimization worked. The ADATA ValueRAM 4GB 2666 was constantly hitting a 0.5-1.2GB deficit when allocating shared VRAM, leading to immediate crashes. I first tried lowering all textures to the absolute minimum, but the game looked like a mosaic and still crashed during map loads—it was a total failure. I then went into the BIOS, enabled 4G Decoding, and manually capped the shared memory threshold at 1.5GB to force the system to prioritize physical VRAM. In the performance analyzer, memory swap frequency dropped from 120 times/sec to 30-45 times/sec, and the game barely holds 30 FPS. I had a problem where my SATA drives weren't recognized after enabling 4G decoding, but a BIOS update fixed that. Memory temps were 40-46℃ at 2666MHz. Resource monitoring confirms the shared mode switch worked, and fans stayed at 1400-1600RPM.
