[dx69+70] FPS + SetTransform transformation
Ann and Jason Edmeades
us at the-edmeades.demon.co.uk
Wed Jul 16 18:10:53 CDT 2003
This was to be two patches but I didnt save the intermediate files, so
heres the merged version. Again, I only take credit for merging in the
work, the hard bit was done by Lucho.
(Tested againsts wc3, MaxPayne, UT2003demo, OperationFlashpoint and they
all were still playable!)
Note: I had a concern about calling gettimeofday, but I saw it was
already used in dlls\ntdll\time.c and I think I have done the right
includes.
Changelog
Add fps debug channel, so we can see how the d3d code is performing and
their impact of performance changes
SetTransform almost rewritten in a much neater way, and in coordination
with drawprim it significantly reduces the number of times that we
reload the matrixes.
