[Turnip] Flightgear crash #388

Open IntinteDAO opened 2 years ago

IntinteDAO commented 2 years ago

On Android in VNC thanks to Turnip, I decided to see how gl4es works and if there are differences compared to zink (as I understand it, it converts Vulkan to OpenGL?). In any case, I noticed that Flightgear crashes on gl4es.

So this is OpenGL -> GLES -> Vulkan ... That's some transformations!

Thanks for the test, but that will be tricky to fix as I have to duplicate on my side (maybe I don't need turnip to reproduce).

IntinteDAO commented 2 years ago

All in all, I don't know what the chain is. I think GLES is native, but maybe not.

In any case, on Turnip and Zink Flightgear works (but unfortunately on high details, and the smartphone does not do well with such graphics quality, and it is impossible to change :D)

The GL4ES project itself is interesting and I will test different games. Flightgear should work, because I think it supports OpenGL 1.4.
