Hi,

I want to buy a new graphic card. I dont have money for a professionnal series so I 'm interesting to your experience with gamer card.

-Ati had a bad drivers reputation, but in opencl their card are faster than nvidia equivalent.
- Nvidia have a good driver but in professionnel context their gaming card are restricted (to sell their professionnal card ?… )

So i would like to have a feedback to ati user (artefact, crash, etc …)

Opencl1.1 Benchmark [clbenchmark.com]
if some users with a quadro card can do the benchmark for comparaison.

Thank have fun
Thomas

I would have to recommend Nvidia at this point. There is something odd going on with AMD's drivers at the moment that are causing some issues with Houdini (FirePro and Radeon both).

ok thk for recommandation, I will look for gtx580 3go or the gtx680 4go.

have fun

i just got a 580 gtx 3g, i took a a sphere primitve and went to 11 million polygons, it was at 20 FPS in viewport, i could have pushed further

On my “old” gtx 470 with 12,800 millions (sphere polygon frequency 800)
aa 16x, smooth lines , hdr rendering, diffuse and specu

viewport report :
H11 = 1.1 fpm , 0.02 fps
Opengl 1 = 2.3 fps
Opengl 2.1 = 23 fps
Opengl 3.2 = 19 fps

really nice improvement from H11 ! but if i want to select a bunch of point houdini freeze with only one cpu thread at 100%.

Same for selection / deselection of a node seems to not multithread, houdini have a little lag (2/3s)
