What version of Wine and display drivers are you using? In 1.1.26 I
added a bunch of XRender related patches to accelerate already big
chunks of bitblt (less roundtrips to X are needed). In some situations
it can already boost performance a lot depending on the display
drivers. There are more bitblt improvements possible though. For
example in case of SRCCOPY, which is the most common blit operation, I
can save a 'memcpy' by getting rid of an intermediate buffer.

I have some more patches which can dramatically improve rendering
performance soon in cases where programs hit dibsection depth

I can't easily say what is making Visual Studio slow but I guess it is
a combination of slow drivers (fglrx is quite slow) and bitblt
