GEAE8P

What went wrong?
The game has a host of graphical glitches, ranging from nearly complete black screens, to missing/black textures.

What steps will reproduce the problem?
Start the game with D3D11 enabled as the graphics backend.

What version of Dolphin were you using?
3.5-1067

64 or 32 bit Dolphin?
64-bit

Slackware Linux 13.37
i5-2500K @ 3.8GHz
GTX 550 Ti

64 or 32 bit Operating system?

The game uses a projection hack that doesn't work for d3d 11.

So, without using the Projection Hack, D3D11 looks like OpenGL and D3D9 when using the Projection Hack? At least two other users on the forum have confirmed this. If so, this doesn't appear to be a valid issue; if anything, it's one less game that needs hacks, which is good news.

No, without using the projection hack, DX11 looks like OpenGL or DX9 without using projection hack :)

When using hack with DX11, it also looks like OpenGL or DX9 without using the hack !

Game simply does not work without the hack, and that is the main issue which needs fixing

Yo, I don't use D3D9 or D3D11 so forgive me if I misunderstand some things. I thought the forum comments suggested D3D11 played it just fine without the Projection Hack, but I did not read those statements carefully and can't test it myself.

I guess this issue should be about needing projection hacks at all in this game.

At any rate, the game renders everything correctly when switching to 1st Person view without Projection Hacks with OpenGL. It seems the Projection Hacks may fix something specifically with the game's 3rd Person camera that used just about everywhere else.

I've spent a bit of time trying D3D11, projection value does NOT change the graphical output at all (just distances) - I use Windows 7 x64, and the dolphin version does not matter at all. The problem is - and is verifiable by images i've posted on the thread - That textures are often rendered as all black, but it is never all textures. There are times - in the intro and start menu cutscenes for example - where the textures are temporarily rendered properly and then switch to being rendered as all black. Free look does not change the texture rendering at all, so it doesn't seem like a camera issue - it might be caused by internal distances.

Just as a side note: while i was reading through dolphin's documentation, I found something that said when the uv[1] argument of the primitive function TexRect was less than 162, it would render textures as all black. I've just never been able to find where it is called, either explicitly or implicitly, and the debugger has just been unwieldy.
