Open GL3 unsupported on Nvidia Shield Pro?

Essasetic · 07-31-2018, 10:04 PM #1

Hi I'm wondering why I can't run the OpenGL API on my shield. Because I've seen other people managing to get it up and running and I was able to get it working at one point. And I'm pretty sure the Nvidia Shield Pro can run OpenGL3 and above. (And I know Vulkan exists now on Dolphin android but that brings a lot of graphical issues with games I want to play).

I'm using LineageOS 15.1 (Android 8.1 Oreo) any help will be appreciated.

Thanks!

Custom roms aren’t guaranteed to maintain full compatibility with all of nvidia’s extra features like desktop OpenGL. I’m going to be honest. Switch back to stock if you care about dolphin.

It's either I wait until the graphical issues with Vulkan get ironed out. Or I revert back to Nvidia's stock rom. Some of the graphical bugs with Vulkan have already been ironed out with some of the games I've tested. (Metal Gear Solid Twin Snakes and Mario Kart Wii). So I don't think I'll have to wait too long until I can completely forget about OpenGL. All I'm waiting for now is to fix the pink bar flashing in and out of Metal Gear Solid Twin Snakes' cut-scenes and I'll be happy.

Adding on to that I find it weird that one of the most popular android custom roms doesn't have proper OpenGL support. Anyway I'm going to try and wait it out until Vulkan becomes more stable and has less graphical issues because it's the best preforming API and requires less sacrifices to graphics and the emulated speed to get a playable experience.

If I'm understanding the issue correctly, this can only be solved by turning off the "Store XFB Copies to Texture Only" setting.

Yep that seems to do it. Thanks Smile

GPU feature support should be the same as pretty much every custom ROM just rips necessary drivers from the stock image IIRC.

So... How come that's not the case with LinageOS then? Maybe because it's developed by an entire team so they make their own drivers. Anyway Vulkan is making a really smooth transition into android and one day I think OpenGL may be obsolete due to Vulkan. Then hopefully we won't encounter this issue again.

But some custom APIs need some manual tweaking to work - for example the default android-provided egl/gles wrappers clearly won't work with desktop GL - they're likely patched versions compared to what's on AOSP.

LineageOS does not develop any drivers. Its probably that it's not implemented correctly.
