3d coat dx vs gl7/27/2023 ![]() Not surprisingly, Valve is also promoting OpenGL in various ways the same link also has a video from a couple weeks back at Steam Dev Days covering the same topic. (Short summary: DX was able to push new features into the API and get them working faster than OpenGL in the DX8/9/10/11 days.) Anyway, if you have an interest in graphics programming (or happen to be a game developer), you can find a full set of 130 slides from the presentation on NVIDIA's blog. It almost makes you wonder why we ever settled for DirectX in the first place-particularly considering many developers felt DirectX code was always a bit more complex than OpenGL code. Even without fine tuning, they note that in general OpenGL code is around 1.3X faster than DirectX. ![]() There's also the increasing support of Linux and OS X, making a cross-platform grapics API even more desirable.Īt the Game Developers Conference 2014, in a panel including NVIDIA's Cass Everitt and John McDonald, AMD's Graham Sellers, and Intel's Tim Foley, explanations and demonstrations were given suggesting OpenGL could unlock as much as a 7X to 15X improvement in performance. smartphones and tablets use a subset called OpenGL ES-the ES being for "Embedded Systems") we're seeing a bit of a resurgence in OGL use. ![]() Today, the vast majority of Windows games run on DirectX, but with mobile platforms predominantly using variants of OpenGL (i.e. As Microsoft continued to add features to DX, and with a healthy dose of marketing muscle, the subject mostly faded away after a few years. ![]() I was around back in the days of the flame wars between OGL and DX1/2/3 devotees, with id Software's John Carmack and others weighing in on behalf of OGL at the time. OpenGL debates-and we can toss AMD's Mantle into the mix in place of Glide (RIP 3dfx). With the announcement of DirectX 12 features like low-level programming, it appears we're having a revival of the DirectX vs. ![]()
