Direct3D vs. revised OpenGL renderer

Still, I'm still going for the openGL, it's just....lush.

Could you post your settings in the [OpenGLDrv.OpenGLRenderDevice] section of your deusex.ini file?

I demand comparison screenshots of D3D and OGL rendering to demonstrate this supposed superiority.

There's no mystery as to why the Direct3D shots have jaggies while the OpenGL shots don't. The OpenGL settings above are enabling 4x anti-aliasing (UseAA=True and NumAASamples=4), while AA with Direct3D cannot be enabled in the deusex.ini file and must be turned on in the driver settings. These D3D shots appear to have been taken with no AA at all.

ralentor on 20/1/2006 at 22:51

Other than the AA level, I see no differences in the visual quality of those screenshots aside from the D3D shots being slightly brighter, which I prefer. And since there are two known bugs with OpenGL as previously mentioned, I think I'll stick with Direct3D unless someone can convince me otherwise.

Isn't someone going to defend OpenGL? It sure is quiet in here.

Dr. Dumb_lunatic on 24/1/2006 at 10:53

Well I clearly have no idea of the technicalities, so not me.

Erm, one thing I do notice (all AA stuff aside, presumably..or maybe not..) is that D3D gives me sort of..hrm..how to describe it..very subtle horizontal lines across the screen, like the scanline detail texture was being applied to all geometry (I can't remember if it was EVERYTHING, or just level geometry.it's been a while since I used D3D). Normal detail textures were also there, but there was just a sort of line-iness to the whole thing.

OpenGL comes out much "cleaner". With nice smooth surfaces with normal detail texturing and no lines.

Any ideas?

ralentor on 24/1/2006 at 16:41

I haven't noticed any subtle horizontal lines with Direct3D on my GeForce 4600, and I'm pretty sure I would've noticed them if there were any, but I'll check again next time I play. Maybe the lines are there with D3D on a Radeon but absent on a GeForce.

ZylonBane on 24/1/2006 at 18:10

The only consistent glitches I've noticed in D3D is some pixel-wide trash around the edges of the screen. I always chalked it up to an AA artifact.

I don't suppose OpenGL fixes the disappearing walls in the MJ12 base in Hong Kong?

I find OpenGL gives framerates about 20-50% higher than D3D, looks cleaner, and makes me feel like I'm not a slave to the Redmond Ogre. :cheeky:

Not using D3D rendering, or more specifically, advocating games which use OpenGL, will push more game developers to build games which can be run on multiple platforms, which is precisely what Micro$oft doesn't want, because all of the solutions in Linux for running DirectX have turned out either substandard, or limited to more dependence on proprietary code. By supporting OpenGL, you support your own right to not be restricted by monopolistic practices. [/pseduopolitics]
