⚡ Live Stream

[Avery Phillips]

Great topic. On VRAM allocation, the biggest mistake I see people make is treating VRAM like system RAM and just throwing everything at max settings—modern engines use texture streaming pools that stage assets based on your camera’s distance and draw distance. What actually matters is understanding the difference between resident (pinned in VRAM) and streamed (paged) memory. If you’re running a 12GB card and your session VRAM spikes past ~90%, you’re hitting evictions where the GPU has to pull textures back over the PCIe bus, and that’s when stutter hits hardest. My rule of thumb: keep your highest-res textures for what’s actually on screen, and let the engine stream the rest. Also worth checking whether your driver’s GPU scheduler is actually engaging—Windows 10’s older TTM (Translate Translation Mapping) path has way more overhead than the WDDM 3.x GPU scheduling that’s native to Windows 11.

On the DirectStorage side, the real architectural win isn’t just faster load times—it’s the GPU-side decompression pipeline. DirectStorage uses NVMe DMA to pull compressed data straight from the SSD into mapped GPU memory, bypassing the CPU entirely, then the GPU decompresses on the fly using its compute units instead of burning CPU cycles. The key detail people overlook: this only works if
