# Information
Due to an inefficient driver OpenGL will perform poorly on INTEL GPUs. The driver lacks performance optimizations , several mandatory extensions are not supported as well as lagging behind in OpenGL version support.
Intel doesn't seem to care much about providing fully working drivers. Even Kaby Lake doesn't support OpenGL 4.5
There is a PCSX2 discussion thread regarding the mentioned issues [here](https://github.com/PCSX2/pcsx2/issues/1716).
***
### List of issues:
* **OpenGL support. Currently the support on Windows is very lacking. As a result many OpenGL functions and Extensions will not work. [List of OpenGL version support on Intel GPU Generations](https://www.intel.com/content/www/us/en/support/graphics-drivers/000005524.html)
* **OpenGL support on PCSX2
Below Ivy Bridge - nothing
Ivy Bridge OpenGL SW yes / HW no
Haswell and above OpenGL SW yes / Hw yes
***

### QA:
**Q I'm not able to run OpenGL?
A: Check your generation. Anything below Ivy Bridge won't run on Windows. Ivy Bridge only supports Software rendering on OpenGL.
**Q My graphics are corrupted ?
A: Set Blending Unit Accuracy to "None". Intel GPUs don't support GL_ARB_texture_barrier hence you will no be able to use the feature.
**Q How is performance?
A: Performance should be better on OpenGL compared to Direct3D even with the missing functions and extensions.
