Lowest spec machine you've seen Left4Dead running on?

I can only state that TF2 runs nicely on my mate's lappy with a Radeon X700...the CPU is an Athlon 3700+ which is probably about as fast as the 2ghz Pentium M so I'm surprised your friend is having problems.

I know the Left 4 Dead engine has bells and whistles on top of the TF2 build, but still, I'm surprised.
 
According to those benches, an A64 4000+ with GTX280 has min fps under 20 in 1280x1024 0xAA 0xAF. The 5000+ X2 (which has the same clockspeed and cache) meanwhile has a minfps over 30. So it's pretty obvious that you really need a multicore processor to play this game at an acceptable framerate.

...at high settings and a reasonable resolution. Playing the game on lower detail settings at a lower resolution and on an external server (so a lot of the AI calculations are done by the server and not your own PC) lowers the strain the game puts on your PC quite a lot.
 
I didnt find this game that demanding but I never hosted a server so Aekeron is probably right there

I often run games on a 2900xt at 2d clocks, the lowest they'll go and most run fine including this one. 1600x1200 res
 
Any P4 I have (including under spec 2.8Ghz, 1.5GB, nvidia 6600) have had hyperthreading and have run the game quite well so I wonder if the game uses the virtual dual core the HT gives, anybody know?

Though probably academic now, lowest clock speed cpu I've played L4D on is 1.73Ghz Intel Core Duo (double Core Pentium isn't it?) with 2GB RAM and ATI X1400.
The lowest spec pc is mentioned above as a Pentium 4 2.8Ghz HT, 1.5GB RAM, Nvidia 6600 AGP video card. Hopefully this'll help someone even if not OP...

Cheers for the input. I'd imagine that it does make use of HT, but I'm sure someone else can confirm either way.

I'll get more details about how well it runs and at what settings and post back with my friend's laptop specs again - as they are possibly lower than the above P4 system.
