The Windows driver supports up to OGL 3.1 but the hardware is capable of OGL 3.3, intel were too lazy to write a Windows driver for the hardware to utilise all of the OGL capabilities there isn’t much we can do about that. These fixed drivers basically eliminate the need for the compatibility shim in 95%+ of scenarios. I tested the compatibility shim fix myself anyway and having to apply it on a per application basis is a massive pain in the arse, even then the shim fix won’t work for all software which is why this driver was born, outside of niche scenarios (eg; software wanting OGL 3.3) this driver restores full OGL functionality, fixes hardware encoding acceleration, possibly some other bugs too.
EDIT: Also updated link in first post with the new all-in-one driver package, no need to do anything other than install the driver.
