DirectX 12 uses more VRAM?
When moving to our higher end GPUs we started by looking at the VRAM consumption of the title when using DirectX 12, which give us very similar results to when we were using the lower end GTX 960 and R9 380 GPUs. Right now we do not know if this increase in VRAM use is limited to only this game or if it will affect other DirectX 12 titles, but we will certainly be looking into it when more DirectX 12 games launch.
At 1080p we can see that VRAM consumption increases significantly when using DirectX 12, increasing by as much as 350MB on AMD's Fury X and as much as 600MB on Nvidia, which means that on higher resolutions that we actually run out of memory on our AMD R9 Fury X.
At 4K Standard settings and above we actually run out of VRAM on our R9 Fury X, which is a real shame given how well this GPU usually performs at 4K.
Please note that we do not know at this time if these increases in VRAM use or due to the beta nature of this title or if it will affect any other titles, but we will be looking into this when more DirectX 12 titles launch.
Personally I think the Mantle development was invaluable to AMD. Not only on the software side but the hardware side as well, allowing them to think ahead and put in features like there advanced queue scehduler's in there GPUs even though it wasn't being used until now. Luckily it worked out for them in the end.Quote
