For a while now I've had an on-again-off-again opengl issue. Mostly it works fine, but sometimes it's not there and software opengl is running instead (with a hefty performance penalty).
Today hardware opengl is off and I can't find any way to turn it back on.
I'm running a Dell M4300 with XP and SW2009SP4. The issue first reared it's head with SP2 and had been behaving itself with SP4 until today. I'm running the SW tested driver, previously a reinstall of that and a reboot or two would help. But not today.
What else can I check?
I've reinstalled the drivers twice and rebooted half a dozen times. No improvement. I repaired the solidworks installation, again no improvement.
Are there any checks I can run on my graphics card?
