DX11 API with feature level 10. Anyone playing around with that on this setup? Cuz the API is leaking memory big time on Map() and UpdateSubresource(). Truth be told I didn't do anything major with Map() before and the only major change lately was the new drivers. Leaks with hardware layer, works fine withe WARP and REF. Simply calling Map() leaks, no need to copy anything to the mapped area. Leaks actually happen when calling Present() but only if Map/UpdateSubresource is used in a frame. Fun, fun, fun.
