(fill it with some trivial pixels then swap buffers). that's it. it doesn't benchmark anything else (and nothing in real life - games or otherwise works this trivially). glxgears may have been complex-ish to do 20 years ago. it's been trivial for the past 12-15 years to the point where it almost equates to how fast u can write to vid mem as that will be the constraint. -- ------------- Codito, ergo sum - "I code, therefore I am" -------------- The Rasterman (Carsten Haitzler) [email protected] ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
