I've recently built a PC featuring a Ryzen 3 3200G with 12GB of RAM (an 8GB stick at 2400MHz and a 4GB stick at 2133MHz). I attempted to overclock it and set the UMA frame buffer size to 4GB, which is the maximum of 16GB available. It worked fine for a few days, but today I noticed that Resident Evil 4 was lagging. Upon checking MSI Afterburner, I discovered that the integrated GPU was only utilizing 2GB of memory. When I went into the BIOS to adjust the settings, I found that the highest I could set the shared memory to was still 2GB. My motherboard is an AB350M-DSH V2-CF and I'm running BIOS version F50 with AMD AGESA Combo-AM4 1.0.0.4. Any advice on how to increase this?

Changing the iGPU memory settings doesn't really help much. The iGPU uses system RAM as needed, but if it's hitting a limit, it's probably just not powerful enough for the game instead. RE4 might need more than what the integrated graphics can offer.
Actually, I found that when I upped the memory allocation in the BIOS, it did allow the game to use more VRAM. It improved performance a bit, even though I had to lower the settings.
