Good news! I have confirmed that the bug we were having to work around was fixed in 10.10 & so from 4.6 onward the Intel GPUs should see a significant performance increase when running on 10.10 and later. How much faster will depend on the scene complexity, but it should be noticeable in almost all cases.

Can you give a figure for the speed increase? If you want more money from me to upgrade to the latest Unreal engine I need to know precise figures! Will it work with Intel HD3000 now?
