Windows 7: DirectX vs OpenGL

14 Jan 2010   #11

@Home/Work: Windows 8.1 Enterprise x64

I also like open source software but... I don't know why people never mentioned that in most cases DirectX performs lots faster than OpenGL.
I'm gamer since 1990 and PC gamer since 1996 and since that old times I always had lots more FPS with DirectX than with OpenGL.
For example, last week I've tried Dolphin, an Wii emulator for PC (just for test purposes) with some Wii games that a friend of mine have and emulator's devs said in forums that they're focusing on OpenGL plug-in more than in Direct3D because an stupid bug in Direct3D's plug-in they don't want to fix, arguing that OpenGL is best for unknown reasons, but... anyway, the thing is that with same graphics capabilities and also in the same game, I've got around 30~40 FPS more with Direct3D than with OpenGL, making Direct3D that lots of games can be playable at full FPS in my hardware (see my home PC in my specs) and getting OpenGL at just 20~30 FPS... that means half speed gameplay, man!
This is just an example, but I've experienced it a lot in the past, even with commercial software and benchmarks, not only in my hardware, it have happened in every hardware I've tested. Since the old SiS 5596 I used to use in 1996 to the GeForce GTX295 SLI that is using a friend of mine with updated drivers and everything.
I don't know if somebody experienced the same or it's just my bad luck.
