    I don't know because kde 4.5 desktop effects need some hacks to work with Intel cards, so I still not tested it with LLVMpipe.

    We were comparing CPU vs GPU - or did you have something else in mind?

    Where does the GPU driver run?

    Still not sure what you mean?

    My point was that llvmpipe is a pure software renderer, even simple GL stresses the CPU pretty hard - using a compositing manager driven by llvmpipe wouldn't leave much room to do anything else. Power usage is also quite likely to be a major issue compared to doing it on the GPU.

    I use kde 4.5. Its compositor do work only with proprietary drivers because it makes use of opengl2 extensions still not supported by open drivers. So I simply do not use it at all and I don't know if it works with LLVMpipe. Anyway kwin 4.4 should run quite well even with llvmpipe.

    Sorry, my previous post was a reply to Vincent.

    I tested Extreme Tux Racer and Torcs (same specs as above) and both were nearly playable at 10-15 fps depending on resolution. That's strange, but it seems llvmpipe's speed depends only on resolution, and not on the number of objects/detail/filtering. Anyone can explain this?

    Oh jesus....

    If an app stresses the CPU then the CPU won't have so much time for the GPU driver and thus it will also be noticeable on the GUI.

    You're the most horrible troll on the planet

    We're talking about _llvmpipe_ - a software rasterizer. Think of it as an emulated graphics card, the GPU does not enter in to it.

    And I must say, being called a troll when all I do is trying to figure out what your point was... isn't nice.

    I don't mind being wrong, there's always an opportunity to learn something new, but I really want to know what it is that I'm wrong about?
