Operating System: Windows XP Pro (5.1-,Build 2600)
CPU: AMD Athlon, MMX, 3D Now, ~ 1.0 GHz
SYS Mem: PC 2100, 256 Meg, DDR
Video: ST Labs ATI Radeon 9000LE, 128 Bit 128 DDR mem, 250MHz Engine Clock
Direct version, 9.0b 4.09.0000.0902
I can see several big problems with that system.
First of all 256Megs of ram won't be enough for any modern game if you run WinXP. 1Gb is required for games such as lomac, Il2 and the likes.
Secondly a 1Ghz cpu won't cut the mustard. It has been outdated in games for 1+ years.
Third: Ati Radeon9000 can't handle 3D intensive games. The fact that yours is the LE version makes it even worse (LE is the slowest form of ATI cards.) If you 'upgraded' to a 9000LE I can tell you, you made a BIG mistake there. Waste of money.
What's left? Oh, Directx9b is up to the task. No need for a change there.
A quick low-cost solution for you would be to move back to Windows98SE which would help greatly on your lack of resources. The 98 is still the fastest gaming platform around and it's your best shot if money is THE object. If you can spare a few bucks you need to upgrade all 3 of your main components, most importantly the radeon9000LE
has to go.
I personally run A64 3000+ with radeon9500pro and I get around 60fps in tower with little over middle slider positions. It's not good by any means but I noticed an increase in fps from 20+ to 60+ when I upgraded my cpu from 1900+ to 3000+. The bottleneck now clearly is the 9500pro.
