NVidia CUDA test 1, elastic deformation

By the colors of the $PS1 on that terminal, I smell Gentoo! ;-)

condom?

[dibbuck]

this isa visually lame demo - I could do that on an old 486 more or less

only specific tasks perform better on GPUs than on CPUs. So the main challenge is to let the two processing units do the kind of task that they were designed for ;)

[Hrakleus]

9900GTX!!! (GTZ would be an awesome name!!)

[rijatru]

Yes. Cpu`s still are a bottleneck.

[rgsgww]

dont forget cpu! without cpu being researched....gpu will suffer

[freakazo]

or just move cpu tasks to the gpu ;)

[rgsgww]

lol yeah but id liek to see some crysis (yeah the story sux) on 2 quad intels and with a nice nvidia quad sli...damn that would be expensive

[freakazo]

Or the crysis physics engine and AI engine ported to CUDA and then you can have two 8800gt 's in sli with some old CPU like the amd 3800X2 and you'll get 10 times the performance than 2 quad intels ;)

that's what the whole CUDA thing is about!

did you see that nehaleam 3.2GHz idf demo? 60K particles at 15-20 FPS, Nvidia then demoed it with a 9800 with CUDA and they got 300FPS.

[rgsgww]

oh yeah i forgot about that, but i saw some of the benchmarks for the amd 3800x2 it diddnt look too good

[freakazo]

That's exactly my point, get a 60$ CPU and a graphics card to do all the physics via GPGPU and you get more for less at the end!

[rgsgww]

and just imagine that with an even more powerful processor

[freakazo]

urgh

[rgsgww]

what????

[snevelin]

It's not going to make much difference if it's offloaded to the GPU, that's why.

crysis wouldnt do good on cuda with physx because its already gpu bound. the average dual core from amd can easily handle the physics in crysis. however to run crysis on high needs a very high end gpu. games like gta 4 need to be physx and cuda enabled because they are cpu bound.

[Galient5]

@l0lum4d exactly, it would put extra strain on your gpu, while you cpu can run it fine, cpus can however not handle physx so it would be all in the gpu. it be nice to have physx in crysis though (other than the probable fps drop)

[l0lum4d]

@Galient5

Yes, however now that DX11 is out, it's a great time to use CUDA and Physx. Even though Crysis is GPU bound, the new Nvidia 4xx series would have no issue running Physx on top of Crysis. A lot has happened in 11 months, it's really quite amazing.

[Galient5]

@l0lum4d yep although if they came out with a new crysis (vrysis 2 doesnt count it has sime major optimization0 it would be hard to run it with physx,

[dturbiner]

insane!!

GPU programming is indeed the future!
