L4D2 on a 6600GT

So a few weeks ago my "better" graphics card died (granted it wasn't anything great, a Nvidia 7900GS) and I was left with only an old Nvidia 6600GT (minimum required graphics card for L4D2).  Now if you follow graphic technology at all, I went from a 4 year old card to more like a 6 year old card.  Well, I'm cheap and I'm waiting for XFX to tell me if they're going to replace my card or not, but I still want to play games, specifically Left4Dead2.  So after much tweaking, here's how I got it to run smooth enough to play.

Launch Options:

What does that mean:
-dxlevel 81 This forces into DirectX mode 8.1, a lot easier on your graphics card
-heapsize This makes the heap size larger (i.e. more ram available to the game)
-nojoy Disable the joystick support
-noipx Disable IPX support
-noforcemspd Not sure what this does
-width / -height set to the resolution of your monitor (I'm using half resolution, 1920x1200 is too large and FPS is too low at full resolution)
-lv Low Violence, zombies disappear, no blood, less work on your card. (large performance boost)
-novid Disable startup video
-console Enable console (optional)
-dev Display developer feedback in game (optional)

Also make sure to put everything on lowest settings in game, disable anti-aliasing, etc.  Also will want to turn on "net_graph 1" in the console to get the FPS displayed in the bottom right.  With this I can usually pull 20 - 40fps in game, which is playable enough.  Still not quite getting enough FPS in game?  Other things you might want to try:  I run Windows 7, I went though and disabled extra services I didn't need such as Aero, Windows Search, etc.  Granted my computer looks like Windows 98, I honestly prefer it this way.  If anyone can think of other things, post them in the comments and I'd be happy to add them to the post.  Now go kill some zombies!

Hit me up on steam if you ever want to play!
