Amount of optimisations for different gpus #380

Closed Sisah2 closed 2 years ago

Sisah2 commented 2 years ago

Hello, i just want to ask, maybe stupid question. What is the amount of gl4es optimisations/exceptions for different gpus. I recently bought the device with the new xclipse 920 but it seems like it should perform better. Is there something i can try to do? Currently tested openmw (which is the only thing where i can test stuff/compile own build) it work "well", but not much faster than 3 years exynos chipset. The second thing is ion fury, which use gl4es too, yet there the performance is 2x-3x lower then on ex9825 (3 years old chipset).

There is very little specific code per vendor in gl4es. Just some minium workaround, nothing related to optimisation. gl4es use extensions exposed by gles hardware driver to improved speed, som maybe the older driver exposed more extension? Also, are you sure your new hrdware have a more powerfull GPU than your older one?

this new one should be a lot faster, yet it seems they dont bothered doing proper opengl es driver and just used angle instead. this is how gl4es initialization look on it. does it miss something important?
