Recently bought Saints Row 4 for Linux. But it needs OpenGL 4.1, when my graphics card(ATI 5470 Mobilty Graphics) haves 3.3. My notebook is running now Ubuntu 16.04.1, Mesa from Padoka PPA. I tried to replace OpenGL version:
export MESA_GL_VERSION_OVERRIDE=4.1COMPAT
export MESA_GLSL_VERSION_OVERRIDE=410
Then i launched Steam and took black screen with sound when game works. Also i tried
export LANG=C
export LC_NUMERIC=POSIX
export force_s3tc_enable=true
But it has no effect too. Notebook Lenovo G565 with AMD processor, Ubuntu 16.04.1 with Mesa from Padoka PPA. How to run game on OpenGL 3.3 without black screen? With bugs, glitches, but without black screen. Thanks.
You cannot fake it. If your hardware only supports 3.3 and the software needs 4.1, you will have to get new hardware to use that software, or you'll have to force software rendering, which will be extremely slow.
Try export LIBGL_ALWAYS_SOFTWARE=1 to force software rendering.
It seems however that your card should support OpenGL 4.4, however it appears the radeon driver does not support that version for your card. Another option would be to revert to ubuntu 14.04 LTS (no newer than 14.04.4), and use the fglrx proprietary driver, which should enable you to use the full capability of the hardware you have.
