How to fix VRAM spikes on Sapphire Radeon RX 7650 GRE 8G?
When the population hits the thousands, the sheer density of building models puts a massive strain on the Sapphire Radeon RX 7650 GRE 8G Platinum Edition. I noticed VRAM usage swinging wildly between 7.2GB - 7.8GB, which caused the frame times to jump all over the place. At first, I tried enabling Smart Access Memory in the drivers, but that was a disaster—it added about 12ms - 15ms of input lag, making the game feel like it was underwater. I realized I couldn't trust the auto-scheduling. Instead, I manually locked the system page file to 32GB on my fastest NVMe partition and dropped the texture filtering from Ultra to High. Checking HWiNFO, the VRAM throughput stabilized from a jittery 310GB/s to a steady 285GB/s - 292GB/s, and the screen tearing finally vanished. I did hit a snag where the system froze briefly during the page file resize, but a quick reboot with Fast Startup disabled cleared it up. Core temps sat at 64℃ - 69℃ with fans humming at 1600 - 1800 RPM. After some digging with performance tools, the frame times finally settled at 5.1ms - 6.4ms, though the 8GB limit still feels like a bottleneck in late-game scenarios.
