I'm currently basing my vehicle code on an example demo that comes with the Bullet Physics source, but it's quite complicated. <br /><br />I'm getting 2-5fps in the FutBuildings 4spp version. Still much worse than the GTS250 :)<br /><br />From looking at the CUDA code, I think that when the 'sun' (sphere[0] in 'Tracer.cu') appears, shadow rays are traced from every primary ray hitpoint, which could explain the framerate dip.Sam Laperehttps://www.blogger.com/profile/05688552048697970050noreply@blogger.comtag:blogger.com,1999:blog-7277449027963623452.post-18887419396269808452011-07-21T11:43:12.226-07:002011-07-21T11:43:12.226-07:00I got 22-29 FPS in the:

50 fps on Futuris...Wow, those are great numbers :D<br /><br />50 fps on Futuristic_Buildings_v2 noAAB_8spp? Damn, the 580 is fast! I'm getting only 0.99 fps with the 8spp version and 0.18 fps with the 32 spp version on my 8600M GT :)<br /><br />It's a shame that the latest exe doesn't work, it could also be an issue with being dependent on the Bullet library.<br /><br />I've uploaded the source code of my last demo to the google code website, so hopefully you can compile a working version on your system.Sam Laperehttps://www.blogger.com/profile/05688552048697970050noreply@blogger.comtag:blogger.com,1999:blog-7277449027963623452.post-80709829224945216192011-07-21T10:03:00.351-07:002011-07-21T10:03:00.351-07:00Your last exe don't work on my computer :(
