Dear mr Kelly,
I'm using a desktop.
Indeed Open GL drawing is not activated.
I've tried updating to the Catalyst
suite resulting in this download but when I run this download my computer restarts, because it can't be executed.
Yes, I tried going to Edit> Preferences > Performance but activating Use Graphics Processor is greyed out.
I'm supposed you're right if you say it's kinda old.
Guess I must buy me a newer one.
