I was using blender 2.76b on a Windows 7 Ultimate, and nothing really weird showed up when I opened blender and the cmd window appeared, before the blender window appeared.

I updated it to 2.77a, and now in the cmd window, it says:

Warning! Legacy WGL is unable to select between OpenGL versions.

Is this a big issue that I would want to fix, or would it not matter?

If I should fix it, how should I fix it?

System specs:

  • Laptop: Samsung Sens R410
  • OS: Windows 7 Ultimate, was Windows Vista Home Premium OEM (according to the sticker on the underside)
  • CPU: Intel Pentium Merom T2390 Dual Core 1.87 Ghz
  • RAM: Installed 5Gb, but can only use 2.75Gb 667 MHz
  • GPU: ATI Radeon X1250 with 256Mb memory with a weird driver that has OpenGL issues. The 3d cursor moves when I drag the arrow to move an object in the 3d viewport. I think this is because I am using Vista drivers, and there are no drivers for windows 7.

    • $\begingroup$ The answer is in your own question: a weird driver that has OpenGL issues. Update or fix those issues. Not really a blender problem it seems. $\endgroup$ – user1853 Aug 6 '16 at 20:42
    • $\begingroup$ I know it's not a blender problem, and I can't fix it. I either have to use the generic driver from microsoft or use a vista driver(which I am using), both of which result in crappy performance. $\endgroup$ – Yubin Lee Aug 11 '16 at 7:11
    • $\begingroup$ Have you tried using Linux on that computer? Using a 64 bit version would allow you to use all of your RAM $\endgroup$ – user1853 Aug 11 '16 at 9:06
    • $\begingroup$ I did try fedora 64 bit, but there were opengl issues. My computer teacher(who loves fedora btw) installed it for me, and he gave up on my computer as well. $\endgroup$ – Yubin Lee Aug 14 '16 at 4:15
    • $\begingroup$ ... In that case... look for a new (used?) computer... $\endgroup$ – user1853 Aug 14 '16 at 4:44

    I reported this as a bug here, and the answer I got was this:

    "Your GPU is too old. You may be able to still use it if you update your drivers."

    • $\begingroup$ This is a non-answer. My Geforce Nvidia GTX950Ti is not too old, and it's using current drivers. $\endgroup$ – Cyberchipz Jul 21 '16 at 21:16
    • $\begingroup$ Well, I have nothing to tell you. That's what one of the blender developers said, not me. $\endgroup$ – Yubin Lee Jul 22 '16 at 4:33

      $\begingroup$ I found out, for me, the issue was a workaround I tried, that didn't work. I had left a copy of opengl32.dll in the blender directory. You might look to see if you have an old copy of an opengl32 library on you system that might be pre-empting your graphics card drivers. Or if your system is really old, you might want to place an updated opengl32.dll into that directory which 'might' fix the problem. $\endgroup$ – Cyberchipz Sep 1 '16 at 16:00
    • $\begingroup$ I don't have opengl32.dll. There was an old issue where the 3d cursor would move instead of the arrows that move a mesh, and the developers told me to put opengl32.dll in the blender directory. However, it was too laggy, and I deleted it and stuck to hotkeys instead. $\endgroup$ – Yubin Lee Sep 2 '16 at 9:10

    That is wild. I was looking everywhere for the solution to the same issue. Everywhere mentioned that you had to choose 'integrated graphics' with an Nvidea card. However I had an AMD card and it was not that old. The sluggish GUI of Blender was driving me nuts. It was the latest download (2.79).

    Turns out it was because I had issues using 2.78 with remote desktop, due to the version of OpenGL. I put a 32bit version in the same folder and it would work while using RDP. When I installed the new Blender, I had not removed that DLL file. That was it. I deleted the file and the problem cleared right up!


    I have solved this problem by following method:
    Open windows explorer and type in %appdata% find the Blender Foundation folder and delete it.

    This might be happened due to some conflict in startup application preference.

      $\begingroup$ Do note that doing so will delete your startup file, user preferences, and some addons. $\endgroup$ – David Nov 24 '17 at 13:31
