Lowest spec machine you've seen Left4Dead running on?

A friend of mine didn't have much luck with running the L4D demo on his old laptop (PentiumM2.0ghz, ATI X700graphics, 1gig ram, WindowsXP) but I'm kind of hopeful that there's some kind of tweaks he can do to get it playable (albeit in *low* settings).

Anyone got any tips/tweaks to try and an example of a very low spec PC you've seen L4D run acceptably on?

Thanks :)

I used to play CSS on a ti4200. So really old school might work, the new crap gfx cards really are unredeemable



Check out the steam forums for low spec configs to tone down every special effect, thats how I got good fps years ago.


If you have a new but crap dx9 card then force it back to dx7 and see if that helps
 
i really dont see you getting it running on a cpu that slow - not without overclocking.

Keep in mind that a pentium M is clock-for-clock far better than a P4 so it's similar to having a (single core admittedly) c2d of similar clock.

Thanks for the info so far people - I've also had other source engine games playing on a ti4200 but L4d seems a little more intensive :)

/re multiplayer vs singleplayer cup use, I agree - I've got a dedicated server that the person can use whenever they like however so that's not an issue.
 
Pentium M is the forerunner of the Core series, so don't write it off.

If L4D uses the source engine I can't see why that machine would have problems, maybe the amount of VGA memory is proving a stumbling block? Seems a bit stupid though since all Radeon X700s had at least 128MB and were 8-pipeline graphics cards. I have a lower spec laptop that works fine with Half Life 2 etc.

Edit:

# Operating System: Windows XP/ Vista
# Processor: Intel Pentium 4 3.0GHz/AMD 64 X2
# Memory: 1GB RAM (2GB for Vista)
# Free Disk Space: 7.5GB
# Video Card: 128MB RAM and Pixel Shader 2.0
* nVidia GeForce 6600/ATI Radeon 9600

Doesn't like your processor I guess...

The Source Engine of 2004 (HL2, CSS) is different to the Source Engine that L4D uses. Even with all the fancy features turned off and all variable settings turned done to their lowest it's still going to be more demanding than comparable settings in say HL2.

I am aware of that, I'm just wondering if the processor type is causing the problem because the graphics card and RAM meet the minimum spec.

It sounds possible. Unfortunately, the said laptop is in Slovakia, where my friend is working at the moment. I won't get a chance to mess around with it myself until near xmas when he comes back over to visit family/friends etc.

I've got a feeling that the laptop might just need a fresh install of windows and the cooling given the once-over - another friend with a 2.2 ghz C2D and 8400M GS found L4D unplayable until he cleaned the dust out of the vents. The joys of laptop cooling :)
