OK let me put up my cmputer specs, this should help.
Processor:
Intel(R) Celeron(TM) CPU 1400MHz
Memory:
254MB RAM
Sound Card:
Intel(r) Integrated Audio
There we have your Problem.
- CPU is a celeron, meaning a castrated Pentium that would be only about 1000 to 1100 MHz compared to other CPUS. (remember this game depends more on your CPU than on your GPU)
-Your Ram is not enough, as you have a Intel Audio, which means that your Driver is doing all the work .)
1 not really, Celeron 1400 = Tualatin = 256KB L2 cache, 100MHz FSB = AMD XP 1600+ Performance = decent for Quake3, will do for Trem
2 Ram is OK, trem takes only about 150-200MB, XP should take ~50MB
3 Audio has ZERO performance impact
And now about the main problem :
I found your post here
http://forum.americasarmy.com/viewtopic.php?p=2285359#2285359and well, bad news, You got served with a "Business computer for running M$ Office" and nothing else :]
1 i810E = worst intel chipset ever since FX
2 GeForce4 MX 440 = poo
There is nothing you can do with this computer other than upgrading to new one.
You can do it on a cheap upgrading mobo/cpu/ram/power supply/gf/case if yours is a miniATX (I suspect it is).
Go buy Sempron/Venice 3000 and ASRock 939Dual-Sata2 combo, this CPU will OC to 2.4GHz out of the box. Buy 1GB of ram and GF6600GT and you will be set for a year of current crop of games.
If you are desperate on money then you can go to bios and try to set
CAS Latency, RAS to CAS and RAS Precharge to 2 (default is "default" or 3-3-3), or/and bump FSB a little (to 112MHz wouldnt hurt your system).
Installing Ubuntu wont hurt you either.
