Ok there is definitely problem with DirectX plugin in r5081 version. I just played Muramasa which is 2D game and same freeze happened. FPS drop to 0, vps and % stays same and music continue.
Some will disagree but I recommend to drop to earlier rev, 5050+ seem to currently have flaws that older builds didn't have. I find the late 4800's and early 5000 very stable and good.
It must be build related, I got 4 or 5 color blades now in Muramasa and past level 16, there was not a single crash, black screen or graphical bug in the game.
Its old threat, but it may have been very likely due to unsupported by Intel compiler build. I had more similar problems everywhere till I switched to VC++ builds(mamario).
