Add support for using WARP software rasterizer with the D3D11 backend #178

Closed kg closed 9 months ago

kg commented 9 months ago

by setting FNA3D_D3D11_USE_WARP=1

WARP software rasterizer ships with Windows and is fast enough on multicore machines to be useful as a debugging tool (to rule out driver issues, etc) or even as a manual fallback if the user has a bad GPU.

The refactoring changes in 37ec1d9 seemed to have introduced a severe bug - see #179.

Good catch @Popax21 , I didn't notice it since I didn't do a fresh local build after applying the code review suggestions.

Will merge the fix as soon as it's submitted!

Well, the fix is just swapping the options around for both ternaries. Since it's such a simple fix I was under the impression that going through a PR might be more effort from the overhead, however if it's easier for you I can quickly create one.

Go for it, I'll be in the office in a bit so I can merge and then rebuild fnalibs as soon as I'm in!

Dang, seems like I missed the time window by just a bit .-. (context: commit fcfab15 just fixed this)
