big ol' benchmark patches, anyone?

March 5, 2007 | 9:37 pm

Hey,
so in another thread I was sulking, complaining that there were no
really strenuous tests for Jitter that I could put my new GFX card
through… and then I thought I might ask here, if anyone wanted their
gl masterpieces tested on a geforce 8800 gts – maybe you could get those
last 5-10 fps that you wanted?

I’d love to load up some things and make this workhorse flex a bit. Send
it over, warts and all :-)

Andreas, i would be happy to know how your 8800 handles gpu to cpu readback.
i understand there are custom x1950 with enhanced support for this operation
(1600$~), and that its not recommended but still. interested.

my cpu takes about 35-40% of the task manager with this bumped up jitter
example.

also of interest is capturing several hi res gl objects, inside the gl
rendering chain.

Same here. I am on an e6600 processor, so that would be 40 percent of one core out of the two, though. And I’ve done some bigger gpu->cpu things while learning jitter that I think did a lot better. Can’t remember which though.

That is really interesting to me, too. How do you propose to test this, though? I’d love it if you had a clipping from a patch we could use.
