how can i set unity opengles version at runtime, not use playersetting.SetGraphicsAPIs

how can i set unity opengles version at runtime with android, not use playersetting.SetGraphicsAPIs. cuz my game on some android old devices must use opengles2.0 to build apk. some shader is not work correctly. i do not want to build two apk for diffirent devices.

 

I know what you mean. but sometimes some old devices which check support opengles3.0 and use it. but shader do not work correctly. That exist in some old android devices. i come from china. there also has some old devices has that problem. so i just try other way to solve it. thanks for your answer.

 

Is this still impossible to force opengl (or other api's) other than via commandline? We'd like users to be able to boot in opengl as a workaround for some compatibility issues some users have been having with DirectX on older machines... but there is no way to specify a commandline in windows store builds..

 

I have two builds for the Android platform where "BUILD A" uses OPENGL ES 2.0 and "BUILD B" uses OPENGL ES 3.0.
Both builds also uses the URP Post Processing. I have noticed that the game runs much faster when it uses OPENGL ES 2.0 in a Samsung J7 Prime phone (Android 8.1). I also tried running Build A (OPENGL ES 2.0) in a Samsung Galaxy S7 (Android 6.0.1) and it works fine. HOWEVER, the Samsung Galaxy S7 doesn't have the Post Processing Effects when it uses BUILD A, but has the post processing effect when it uses Build B. I really don't know what to do at this point, I want my build to (1) perform faster, (2) have the post processing effects and at the same time (3) support Android 4.4 version and above. Am I missing something in the Player Settings to enable post processing for OPENGL ES 2.0 with the Samsung Galaxy S7? I just really don't get it that even if Samsung J7 prime uses Build A (OPENGL ES 2.0), it shows the post-processing while Samsung Galaxy S7 does not show Post Process when using Build A.
