On some (mostly older, integrated) GPUs, the normal GPU texture cache update path doesn't work well when running on ANGLE, causing CPU stalls inside D3D and/or the GPU driver. To reduce the number of code paths we have active that require testing, we will enable the GPU cache scatter update path on all devices running with ANGLE. We want a better solution long-term, but for now this is a significant performance improvement on HD4600 era GPUs, and shouldn't hurt performance in a noticeable way on other systems running under ANGLE.
