Solving 8K VRAM bottlenecks in TLOU Part II with RTX 5090
It's honestly ridiculous—I bought a top-tier 5090 and I'm still seeing frame drops at 8K. It felt like a slap in the face. The 24GB of GDDR7 on the Manli RTX 5090 D v2 has insane bandwidth, but due to some driver scheduling nonsense, the VRAM usage was hovering at 22-23.8GB, causing constant resource swapping. I tried dropping the textures to 'High', but the loss in detail was obvious and I hated it. I eventually used NVIDIA Profile Inspector to force a VRAM pre-allocation mode and tweaked the system page file write speed. Checking GPU-Z, the memory clock stayed locked at 28Gbps, and the drops went from three times a minute to basically zero. I actually tried an extreme overclock that caused some slight chromatic aberration, so I had to dial the core clock back by 50MHz to get it clean. Temps are 62-68℃ with fans at 1600 RPM. I've exported the profile so I never have to deal with this again.
