So I got the chance to play Thor on a powerful machine today. A very powerful machine. An 8 core, 3GHz each machine with some insane ATi GPU. It ran at 180 fps, looking at all the water, at 1024x768 with 4x FSAA and highest precision shaders. The water looked awesome. Everything looked awesome, in fact.

Except the fire.

Now, the fire wasn't even animated. Just a static, low-poly model of a flame.

GPU Gems 1, I say unto you. I'm pretty sure your grass shader comes from chapter 7 of said book, so read up on the fire mechanism proposed in chapter 6 :P

It'd be pure awesome.

1024x768 on an 8-core? Buy a decent monitor for that baby please! ;-)

Number of cores have nothing to do with resolution. In fact, sauer can't use multiple cores. You'll get more performance with a single core 3.2Ghz processor. Also, ATi sucks. Dual 8800GTX FTW!

Well, I might have been trying to gloat about the machine more than anything else >.>

Actually, I was just trying to keep the res down. Turned out I didn't need to. Meh, I say unto you.

The fire model (which has been in there since around... umm... around 2000) isn't animated, and yes, it is low-poly. There is a command for the console: /particles X , where X is a number portraying to the particle effect that you want. This has 2 fire particle effects, one being a opaque fireball and another being a slow-moving rotating transparent fireball. I haven't played around with it enough, but I know that you can change the colors and stuff like that.

crap... the command really is: /newent particles X .

need to do more mapping :)

It can... and does actually :P for the server browser!

Quad GeForce 8800 Ultra's.

Beat that.

So, you have a nonexistent motherboard from the future? Nope, I can't beat that.

They have quad SLi out dude. Google it.

not for 8800's
it is ONLY for the 7950GX2 GPUs

http://www.slizone.com/object/slizone_quadsli.html

quad SLI is actually just two double-stacked cards. There are only 2 PCI-E slots used in this configuration.

Motherboards exist that have 4 PCI-E slots, but those are AMD motherboards, and do not support SLI at all.

3x SLI is coming out for every card on their new 780i chipset, but hasn't been released yet.

ALSO, the ultra has a hard time fitting in the proposed motherboard.

"They also had a play with three 8800 Ultra’s but it seems like the rigid SLI bridge that connected the cards didn’t fit that well with the Ultra cards judging by the pictures."

I HAVE an 8800GTX SLI setup that I built myself. Don't even think you know more about it than I do.

Haha, don't question shadow on this stuff :P

Nice rig anyway (shadow), tried the Crysis demo on it yet? I heard somewhere that Crysis has no support for multi-core CPUs or SLI GPUs at the moment..

And on topic, 8 cores is useless for gaming beyond Sauerbraten anyway. Quad cores still don't have widespread support yet, let alone 8 core CPUs which aren't even available to the common consumer I think?

That and Sauerbraten is not CPU dependent at all really.

Yeah. Thor runs anywhere between 60-95% cpu (on 1 core) on my Core 2 Quad machine, it would appear there isn't any need for such processing power for sauer as it stands. Probably the only way to utilize such power is to run many copies of the game on one machine...

Though... I just tried running 5 copies of sauer and on the 5th copy my display started messing up... driver bugs I guess.

It is CPU dependant... for calclight, isn't it ?

It's not a gaming rig, it's for heavy video editing work.

Crysis is (I believe) windows only, so that's out :)

But this isn't what I created the topic about!

Oooops my bad. I realized about an hour after my post that it was only for those cards. I don't like double posting, so I just let it sit. Thanks for the pointer!

I'm stuck with one laptop and a Quadro FX 360m. :-(

"Number of cores have nothing to do with resolution."

Of course they haven't, but it's a shame to play 1024x768 on an 8-core nevertheless. ;-)


"In fact, sauer can't use multiple cores."

It can if you play sauer on OS X 10.4.8 or newer - multi-threaded OpenGL. Ok, only 2 cores so far, but better than only one. =)
