I don't see the VRAM reading as a problem but as a feature of WDDM 2.0 in Win10, and i don't think the values are wrong. When running the UE4 KiteDemo in Win8.1, there was constant swapping of video memory at the 2 GB mark and thus there was very bad and noticeable stuttering all the time. After upgrading to Win10 and WDDM 2.0 drivers, the stuttering is completely gone and there's apparently no swapping anymore but streaming as up to 3 GB memory get allocated on my 2 GB card. I've done frametime comparisons between Win8.1 and 10, and as soon as i've hit and crossed the VRAMs max size, games in Win10 run much smoother and allocates more memory than in Win8.1. That's why i was hoping for a positive confirmation from Unwinder.
