Dragonlord, I have a very similar setup to yours, and my CTD situation is very similar also.
When it decides to CTD, it will keep doing so more frequently until I give up for a while.
I had an X-Fi card, and sound stuttering went away after I pulled that out, but no change to CTDs.
Mine is:
XP Pro SP3 v.3300
Core 2 Quad 2.6 @ 3.3
EVGA 680i mobo
2x GTS250's in SLI
4G 800mhz RAM @ 825mhz (2.5 visible by XP)
3x WD 1TB drives
No active antivir, no software firewall. I use MWB and manually scan everything I dl.
XP is gutted to 16 processes on startup. Unnecessary services are disabled as well.
I have run memtest86+, un/reinstalled Crysis and MWLL, turned my OC off, turned it back up, checked for any possible conflicts on my PC.
I also use the most current drivers, and EVGA Precision. My card temps top out at ~72.
Where there any assets on screen? Doesn't matter
What was the composition of your team? Doesn't matter. I've CTD'd alone in LAN games too.
Of the opposing team? Doesn't matter
Do you crash more in the early game or late game? Doesn't matter
What map? Mostly Thunder Rift, Clearcut, Extremity, and Inferno. Others have very few CTD's for me, as do custom maps.
What game mode? Doesn't matter
How many players? Generally more CTD's when 12+ players are connected.
What was your ping to the server? Usually between 70 and 120, I don't play anywhere where it's higher.
Did you get any logs? Console errors being spammed? Nothing console-wise, generally the CTD's do not generate a new game.log file.
Take a screenshot of the crash dialogue? Not yet, but here's some fun stuff from Event Viewer...
Faulting application crysis.exe, version 1.1.1.6156, faulting module cryphysics.dll, version 1.1.1.6156, fault address 0x000ddad8.
Faulting application crysis.exe, version 1.1.1.6156, faulting module cryanimation.dll, version 1.1.1.6156, fault address 0x0004db72.

Faulting application crysis.exe, version 1.1.1.6156, faulting module msvcr80.dll, version 8.0.50727.4053, fault address 0x0001500a.
What sort of graphics card do you have? 2xGTS250
What driver version? 258.96
What sort of system resources where in use? Nothing except for MWLL. I have tested running with and without TS3 on, no difference.
Do you have any resource monitoring? Yeah, checking task manager every couple minutes like an obsession.
How much RAM was in use at the time? Generally tough to say, as it happens when I'm playing, and I don't run around with r_displayinfo 1 on while I'm trying to play. Generally I see MWLL use from 900MB to 1.2G, depending on the map and # of players.
I do hands-on gaming PC building and maintenance for a living, and have applied everything I know into troubleshooting this issue, with no change. So please don't throw me noob solutions.
I run CCC pack at lvl 3, I've tested with every level of CCC, and the stock game settings with no change.
When the game works, it runs beautifully, so don't tell me my rig isn't up to snuff. A friend runs this mod on an 2006 iMac with a tenth of the CTD's I have.
I stick to Sandblasted, Mirage, and Marshes, they generally crash much less than the others. This may be coincidence but that is my observation.
I have also tested on Win7 x64, in 32-bit and 64-bit, DX10 and DX9, all of them were much worse, CTD's 2 minutes in.
It's hard to swallow this being an individual PC issue, as it's the only program on my PC that's ever crashed.
However, I would really love if this helps in any sort of way toward fixing it.
It's difficult to want to participate in a league where CTD=loss when this still an issue.
