Will begin with our first OpenGL program. If you choseĭirectX my tutorials won't help you very much. I hope you chose OpenGL, as that's what I will be teaching. And 13 percent on theRadeon and 24 percent on the GeForce. This is the same pipeline that has been used in computer games. When it comes to graphics capabilities, both APIs rely on the use of the traditional graphics pipeline. If you need to develop for more than Windows, OpenGL is the way to go.

So now you know what separates DirectX and OpenGL, and hopefully you haveĬhosen based on facts which you would prefer, not on myths or opinions. At least there is one agreement: Vulkan runs on both graphics cards in Dota 2 faster than DirectX 11. One major difference is that OpenGL is cross-platform, and DirectX is available only on Windows and XBox. There are differences in how each API handles how vertices are combined to form primitives, which are laid out below. Graphics primitives, such as points, lines, and triangles, are defined as an ordered set of vertices. This is the same pipeline that has been used in computer games since the early days of computer graphics.īoth OpenGL and DirectX describe vertices as a set of data consisting of coordinates in space that define the vertex location and any other vertex related data. One major difference is that OpenGL is cross-platform, and DirectX is available only on Windows and XBox. So what aspect of OpenGL sets it apart from the DirectX graphics component? On the other hand, OpenGL is strictly a graphics API. DirectX supports sound, music, input, networking, and multimedia.

The hack reduces cpu overhead in GSdx frontend (texture validity), it is in common code (so it isn't an Nvidia-GL only hack).Perhaps the most obvious difference is that DirectX, as opposed to OpenGL, is more than just a graphics API. On latest git you can find a new HW hack called fast texture invalidation.

(Note on Linux the proprietary driver is dead, I'm not sure Linux users will ever see the fix)Īnd based on snow engine benchmark, the driver is also slower on DX11 too. And they've initiated a shift to low level API rendering. AMD took action on openGL/DX11, they just gave them up. DX12 is out, you can't still use it correctly on AMD GPU.

This openGL extension was published (public release) on July 2010 and this extension is a porting of a DX9 feature to an openGL equivalent. So yes, GL_ARB_separate_shader_objects is currently broken on AMD HW. It took me less time to post a working implementation of the extension for Mesa than waiting a working AMD driver. And I didn't expect Intel to be broken too but that another story.

And I'm afraid that AMD won't fix all their DX11 GPU drivers (forgot about that too). My mistake is that I expected 3 months of QA, not 6-9. Too much code of my initial GSdx port was hack to workaround the AMD driver (hopefully situation is much better). Let's be honest they doesn't really care about openGL bug on Linux (and likely not so much on Windows neither). They only fix one and the others remain pending for a long time. Quote:The main reason for this is that the developer of the OpenGL code has an nvidia GPU and cannot test/fix things which works differently with AMD GPUs. Keep in mind any public release goes through a lot of testing and QA! In the meantime, please use the workaround (i.e.

which was already in lock-down when the fix was written.) It's scheduled for a future release. Quote:It missed the driver release in March (the one with Vulkan, etc. Supposedly it should work again with the next major version of the AMD drivers, but that's a guess.

There was some code to make it also work (visually) with AMD, but this code was removed few weeks ago. It's not only somewhat slower but also broken visually for most games. DirectX 11 and OpenGL are unique here where they dont have a dedicated object for the graphics pipeline, but instead use calls to set the pipeline state in. Quote:OpenGL is basically (sadly) broken on AMD GPUs until further notice. * OpenGL accuracy is 10 times better than Dx. * OpenGL could be much faster if you're CPU limited (snowblind engine is something 80fps vs 50fps) * DX11 would be a bit faster if you're GPU limited.
