Why is Software openGL selected and greyed out in SolidWorks with my Intel Graphics Card? John Peros November 25, 2013 20:40 If you go to options, performance in SolidWorks, Use Software OpenGL is selected and greyed out (can't be unselected), what can I do about this? Have more questions? Submit a request Comments John Peros November 25, 2013 20:42 This seems to be a SolidWorks forced setting and can be changed in the Registry. Simply go to Hkey_Current_User > Software > SolidWorks > Solidworks 2013 (or whatever version you have) > Performance > Graphics > Hardware > Intel > Intel(R) HD Graphics 4000 (or whatever card you have). In the right, you will see a key called Workaround with a value of 10. Change that value to 9 and re-launch SolidWorks. Use Software OpenGL will now be unchecked. https://hawkridgesystems.zendesk.com/attachments/token/pgsedk5bkq7fawy/?name=Software+Opengl+Reg.PNG Hunter Cordeiro November 25, 2013 20:59 If you don't have permission to edit the registry you can also launch SolidWorks in OpenGL mode from the Rx tool. Start>all programs>solidworks(version)>solidworks tools>SolidWorksRX under the "home" tab in the RX tool there is an option to start SolidWorks in OpenGL mode as well as an option to launch while bypassing the non-default system options.
