DirectX 12 Update Allows CPU and GPU to Access VRAM Simultaneously

GPU Load Stacks (opens in new tab), this permits the CPU to have direct, simultaneous entry to GPU reminiscence. This function can enhance efficiency and scale back system RAM utilization on DX12 headers because it eliminates the necessity to copy knowledge from the CPU to the GPU. The brand new function is now obtainable within the Agility SDK.

We do not know the precise implications of this function, however the efficiency advantages could possibly be substantial. Graphics card reminiscence sizes and online game VRAM consumption are rising yearly. In consequence, the CPU has to maneuver increasingly knowledge between itself and the GPU.
