![]() ![]() They can be implemented by any implementation. The name of each extension starts with a prefix, specifying what type it is.Įxtensions that start with GL_EXT are generic extensions. There are many automatic tools for loading them.Įxtensions fall into 3 broad categories: vendor-specific, generic, and ARB-approved. OpenGL extensions must be loaded dynamically at runtime. For more information, see Get Context Info. It is possible to check at run-time whether an extension is supported or not. That version is often (but not always) the minimum version that the extension can be used together with. specifies a modification to that core version's spec. The exception to this is core extensions, which is explained below.Īll extensions are written against a version of OpenGL. For example, the extension GL_ARB_multitexture (which has been adapted into the core) contains the function glActiveTextureARB and the token GL_TEXTURE0_ARB. The name of the tokens and functions ends with the prefix of the extension. If an extension is supported on a specific computer, it means those tokens and/or functions can be used there. Quite a few of these extensions have been folded into the OpenGL core.Īn extension always contains at least one enum token, or one function. Many of these extensions are old and obsolete in modern programming practice they are listed for the sake of completeness. The extension registry has over 300 extensions listed. The registry also contains guidelines for creating new extensions and has example C/C++ header files containing function entry points and token enums. I didn’t change any settings for ‘3.’.The OpenGL Extension Registry is maintained by the ARB and contains the technical specifications of all known OpenGL extensions. ![]() Select the preferred graphics processor for this program:’ option. I selected ‘Custom Installation’ and made sure to check the ‘Perform a clean installation’ box.Īfter doing all of this and restarting my computer, I opened up the NVIDIA control panel and went to Manage 3D Settings > Program Settings > Add, then added citra-qt.exe and citra.exe, making sure to select the ‘High-performance NVIDIA processor’ in the ‘2. ![]() During the graphics driver installation, I was prompted for either ‘Express Installation’ or ‘Custom Installation’. Then I installed the ‘NVIDIA Graphics Driver’ from the same place (as of current writing, it was version 442.23). Only the ‘Intel Chipset Driver’ was updated, so I installed that. I then went to my laptop manufacturer’s website ( MSI USA) to see if any drivers have been updated since I last installed them. To uninstall drivers, go to Device Manager > Display Adapters > Right Click over NVIDIA card > Uninstall To uninstall software, go to Control Panel > Uninstall a program > Select everything that begins with NVIDIA and uninstall it (you may be prompted to restart your computer several times) I uninstalled all NVIDIA software and drivers from my PC (even though I had all of the latest ones). Note- My laptop is an MSI GE75 Raider 10SE-008. I’ll document my process here in case anyone has the same issue, although you may not need all of the steps to get it to work: I had already tried through NVIDIA’s software and through Windows, but neither had worked for me until I did the steps below. For whatever reason, I wasn’t able to force the laptop to run Citra using the NVIDIA graphics card (it kept defaulting to the integrated one). I was finally able to resolve this, thank you everyone for your suggestions. ![]()
