I think performance tests for dxdiag won't work, but a related idea
might: In the past, I have written a number of microbenchmarks for
various d3d operations like drawing, changing stream sources, changing
vertex shaders, etc. You can find the code at
https://84.112.174.163/~git/perftest (self-signed cert). I'm also
running some of those tests

The overall idea is to use such microbenchmarks to optimize single
operations, in the hope that those optimizations stack up and improve
real games. Most benchmarks have a GL version to find out if there's a
difference between the GL and d3d drivers, or the Windows and Linux
drivers.

Adding more benchmarks to this collection and investigating spotted
performance differences would be a useful gsoc project imo.

There are tests like that in CrossOver, and my experience with them is
that they don't provide too much value. The warnings if libGL.so
doesn't load, or if direct rendering is not available are helpful, but
all other tests go unmaintained over time and become irrelevant.

Wine prints some info like that on the winediag debug channel. Showing
a window instead could be a usability improvement, but that's not
enough work for gsoc.
