Any opinion about this one ? Could it be a good candidate for inclusion in wine tree ?
Hi,
I have used this with StarCraft, running it with and without the DIB engine enabled. I find the environment variable makes it very easy to switch between them during testing, so I am for this (as well as being able to set the default option via the registry).
My experience with the game is that it is actually slower and has a noticible stutter when compared to the non-DIB engine version. This does not mean that I am opposed to this going in, as I know that the blitting code is not yet optimised. In fact, I am for this to go in (provided that Alexandre accepts it).
In the end a dib engine will help a bit for StarCraft but for StarCraft the only proper way for hardware acceleration is to use the ddraw-gl backend in combination with the right rendertargetlockmode. Some games can really use a DIB engine though and that are games like Age of Empires I and II. Though in combination with a DIB engine more changes are needed for optimal performance (e.g. allow the DIB engine to directly draw into a ddraw surface without a memcpy)
