New functionality in the OpenGL ES 3.0 specification includes:2. Version 3.0 is also the basis for WebGL 2.0. OpenGL 4.3 provides full compatibility with OpenGL ES 3.0. OpenGL ES 3.0 is backwards compatible with OpenGL ES 2.0, enabling applications to incrementally add new visual features to applications.
Opengl 2.0 Compatible Driver For WindowsWe are not abandoning the current OpenGL ES 3.0 backend right now: as outlined in the post, we will start working on a Vulkan backend, which will eventually coexist with the OpenGL ES 2.0 and 3.0 backends - and eventually we might deprecate the OpenGL ES 3.0 backend if Vulkan cuts it.As stated in the OpenGL 3.1 Specification (chapter 2, first paragraph). You do not know what version if OpenGL you need Sorry, we cannot help you with that.Edit: Changed post title for clarity (previously Abandoning OpenGL ES 3.0 for Vulkan (and ES 2.0)). There is no other driver for Windows 10. You will be using the Microsoft generic driver, which lacks features and performance, and has no support. One Windows 10, your graphics (and processor) are not supported. Make sure to start the relevant 32 or 64 bit version of the program, based on which type of.Moving to Vulkan (and ES 2.0) instead of OpenGL ES 3.0Forget about getting OpenGL 2.0.Make sure to first identify your Intel Graphics Controller. Intel Graphics controllers support a wide range of APIs. PC games and applications often require a video card that is compatible with specific Application Programming Interfaces (APIs), such as OpenGL, DirectX, OpenCL, or Vulkan.On Android, it is supported in most of the mobile devices in the market. Poor mobile supportOpenGL ES 3.0 works, nowadays, in all versions of iOS. OpenGL ES 3 provided sufficient functionality to implement most modern rendering features and have something that looks really good (as you can see in all the images and videos we posted).Yet, in reality, many things did not go as expected. Single codebase for everything is like a dream come true for writing an engine. Mwestphal (Mathieu Westphal (Kitware)) October 15, 2018, 8:15am 2.The rationale for the OpenGL ES 3 renderer was having a single codebase for targeting all platforms:This sounds really good in theory and we could say it almost works. See About Godot 4, Vulkan, GLES3 and GLES2 for up-to-date information about the planned rendering backends transition.openGL renderer: Paraview 5.6.0 (and higher) on Windows 7 platform: openGL problems.
Opengl 2.0 Compatible Full Compatibility With![]() Opengl 2.0 Compatible Drivers Are NotAgain, this is easy to workaround using batching or instancing and does not happen often, but it's one more step. As they do in engines that use Direct3D 12. Corner cases on NVidia and AMDWhile the Godot 3.0 renderer works great for the most part on NVidia and AMD, there are some corner cases (which are pretty difficult to come by) where the OpenGL 3.3 drivers are not optimized as we would like.These cases are easy to workaround if they ever happen, as they have been the same sort of limitations OpenGL always had (state validation before drawing can take some time).Still many new users may not be aware of this and do things in less efficient ways, yet expect them to work. Poor WebGL 2.0 adoption and performanceWhile WebGL 2 works on Firefox and Chrome (and even runs great on Android mobile), it still does not on the other platforms.Added to that, Godot 3.0 uses quite complex shaders which, while they work fine on WebGL 2, take a long time to compile on Windows due to the Angle GLSL validation and compilation to HLSL.It seems that for nicer performance and compatibility, we will be forced to use WebGL 1.0 for the time being (based on the upcoming OpenGL ES 2.0 backend). Vulkan as an alternativeWhile none of the problems on the desktop side are serious (users have so far mostly reported performance problems on old Intel IGPs, or extreme corner cases), Vulkan was always a tempting alternative to solve them and to ensure we are much safer from driver bugs (after all, this is what the API was intended for). 45 FPS where you would expect 60 if you have an Intel HD 5000). While the performance hit is not really that bad (you can't expect much from this type of hardware), it's enough that compared to other engines (which may use Direct3D and Metal) Godot may seem a bit slower (e.g. The same hardware running Linux has considerably better performance. Blender game engine gamesSupport for 2D meshes, 2D skeletons, and deformable polygons Roadmap changesAs it seems clear that we will be moving to Vulkan on desktop and OpenGL ES 2.0 on mobile and web, further work on the current OpenGL ES 3.0 rendering backend is pointless as it will be rewritten.For now, we will keep focus on releasing Godot 3.1 with the following main features: This pretty much lifts the only barrier we had for moving Godot to it. MoltenVK goes open sourceHowever, today, in a completely unexpected turn of events, it seems Valve has found an arrangement with the developers of MoltenVK (the commercial and proprietary Vulkan over Metal wrapper), ported Dota 2 to it, and got it open sourced.It seems to be a mostly complete Vulkan implementation that runs on macOS and iOS. As we mentioned many times in online discussions, moving to it eventually would be ideal. Having to write a Metal backend to support this OS is a lot of effort for a platform not used very much.Khronos announced many months ago the Vulkan Portability Initiative, which we found really interesting but was far from being functional. ![]()
