if you open the terminal and type: glxinfo
the important line here is 'Max core profile version', which indicates the highest supported OpenGL version.
what does it say for your card?
missed the fact that you have a Intel processor. Likely problem is that you are using only the embedded intel graphic chip instead of your AMD card.
afaik using the option DRI_PRIME you can tell a program to use your "real" graphic card. ie:
Hi immi101 and thank you for confirmation, and advice about DRI_PRIME. When I run glxinfo it shows up as 4.5-compatible. Sorry I'm such a newb I'm not sure how to use DRI_PRIME; looking it up now, and tbh I think it might be above my abilities to change things; seeing some quite complex and lengthy posts about it, and don't want to hog lots of time about this, but thank you very much for drawing this to my attention, as I am learning more about graphics and general settings as I read about it, and will continue that. Sorry, graphics don't cause any issues, and I'd thought it might just be one or two commands would bump up OpenGL and improve things a bit; there's newbs for you, lol. Are there any signs of graphics drivers improving any time soon, to enable everyone to be on the latest OpenGL? edit: just seen article saying drivers out in September, yay.

Hi, just wanted to ask if anyone knew how to be able to upgrade to OpenGL 4.6. I'm on LM 18.1, Radeon r9 255, 4.11 kernel, mesa 17.0.7, Haswell/Lenovo i7 with 16 gig ram. Have tried all the ppa's etc, and am fully upgraded with updates, but can't get past OpenGL 3.00. Thanks.
Mesa is not ready with OpenGL 4.6, but it's not far from it. You can track the progress here: https://mesamatrix.net
You should be able to get OpenGL 4.5 though.
Hi shmerl and thank you for your response and the link about progress. Will have a good read of that. :-)
