[2.1]Not all samples starting (Missing OpenGL extensions?)

Post by Hiklo »

Hi!
I am trying to build and run the open source game "Thrive". After discussing with a developer he came to the conclusion that my system (gentoo x86_64) doesn't have the nessesary OpenGL extensions.
I am currently using mesa 18.1 with OpenGL version 4.5
This is the list of samples not working:

Hdr
HdrSmaa
PbsMaterials
Postprocessing
ScreenSpaceReflections
TutorialCompute01_UavTexture
TutorialCompute02_UavBuffer
Tutorial_Distortion
Tutorial_DynamicCubemap
Tutorial_SSAO
Tutorial_Terrain
V2ManualObject

The developer said that PbsMaterials might share the same extensions as used in "Thrive"
Does anyone have any suggestions on how to make these work?
Thanks in advance! :)

Could you post Ogre.log and the output of glxinfo?

Thanks
Cheers

Sorry for late response!
For some reason, after i redownloaded and compiled it again today, it works just fine. I tested every single one that wouldn't boot up before and they all boot now.
The only crash i experienced was from "ScreenSpaceReflections" and that was only when i moved and the fps got really low.
Anyway thank you for responding, I'll post glxinfo anyways if anyone else encounters this error:

I'll mark this as solved, though I have no reason why it works :P
Thanks for the response!

As you found out, your GPU should've been perfectly capable of running it.

My strongest guess is that the reason you couldn't run our samples is that there was a Mesa bug in 17.2 that prevented sRGB framebuffers from working. If you updated your drivers between that time and now, it would explain why it wasn't working and now suddenly works.
