L4d2 bogging down on me

just bought an nvidia 460 when my 7900gs burned out on me. When a horde comes it can drop my fps to the teens. Is this reasonable? I can post my full list of hardware when i get back to my computer.

Did it do this before the upgrade? To be safe I would run an uninstaller to make sure all the drivers/remains from the previous card are gone. Fresh install (ofc latest drivers) and try again. Also, check the fragmentation if installed via steam.

I had frame-rate problems in general before this new card. The story is I blew my 7900GS, knew nothing about the newer nvidia cards and bought a 9800 (i was thinking it was the old numbering system which made sense to me and figured it would be better than my 7900). The 9800 clearly wasn't cutting it and just gave me poor performance with regular l4d so I knew i needed to upgrade. Then I got the 460.

I never played l4d2 with anything but the 460 as it's a new game. The 9800 was struggling in general (not horde only) just because it was a lower end card.

Thanks for the driver advice, I'll give it a go. Fragmentation shouldn't be a problem, I've got an SSD.

It is not the video card. I played L4D 1 and 2 with a 9800 GT with no issues other than I had to turn off multi-core in the game. Have you tried that?

Q6600 @3.0 4 GB ram XP 64 bit.

Could be the cpu, you have other programs running that could be interfering?

Kinda mean to say this but 2 gigs of ram is cutting it close ya think?? Be sure no other programs are on when you run this (esp. firefox) that will hog up the ram!

I have a friends playing l4d2 on a 9800 and a 460 and they don't have any issues. I am playing it on 7800 GT and have no issues.
However, your CPU is on the low end and my guess is that is your problem.

my specs are:
AMD 9950 X4 @2.6
4 gig DDR2
7800 GT

If you can, try to overclock your cpu.
Overclock it to 2.4-2.6GHz just to see if you get an increase of performance.

Wow what a great amount of responses! Thanks everyone.

Yes I agree 2G may be cutting it close but keep in mind it's XP not a <insert bloaty-ness here>, but I try to resist the "hardware is cheap, throw the biggest angriest thing you've got at it" mentality that is becoming so popular these days. I will try throwing another G or two borrowed from my wife's computer to see if it makes a difference.

I've tried reinstalling (uninstalling first) the video card driver, and installing DX9.0c as per the request of the card when installed. I have some spare parts around I can play with.

Olin, I will try turning off multicore in the game, thank you for the suggestion.

I also agree with attempting to overclock the cpu. It will be my fist overclocking experience but I'm sure I can handle it. If it burns up it might just be time for a new build altogether as it's about 4 years old.

jgiron, you also state that you have friends playing on much lower end cards than I currently have. Do you know if they are playing max settings or not? I haven't specified but I *am* going for max settings.

I'll replace hardware before I give into a DX9 game being too much for me.

Thanks again all.

That's why I said go for 2.4-2.6GHz, as it won't be a large OC but should help see if it's the CPU that's causing the issues in game.
Do you have an AM2+ motherboard?

Run a tool and see if your CPU or GPU is maxed out while you're playing and a horde comes. I played lots of games with 2GB before moving to 4GB and didn't notice a huge impact

My motherboard is:

Ollie, I will try that also.

I am the one with the low end card and I play at medium setttings, my firends have a high end card 9800 GTX and 560 GTX and play at high settings, they also have higher end cpus (core 2 duo @ 3ghz and a core i5 at 3ghz)

Yea, I'm more leaning towards a lack in CPU power. I have a 4870 1GB now, but played just fine on my older 8800GT. The difference between mine and yours (9800GT is a little better than the 8800GT) is the CPU, I have a core two duo E2180 @ 3Ghz.

Ok so the list of things I have tried is as follows:

Software:
Turning off multicore
Uninstalling and reinstalling card driver
Monitoring CPU usage (never went over 70% even during a horde)

Hardware:
Tried adding more RAM
Tried using a more powerful PSU

I just noticed that I missed a suggestion of watching to make sure my GPU isn't maxed out, so I will try that.

Other than that all I have left is OC'ing the cpu, but if I'm only at 70% during hordes doesn't that mean it's likely not a CPU issue?

I verified that my wife's computer doesn't bog down like mine. However she thought she was at full settings and wasn't. For anyone else trying to replicate what I'm seeing make sure you've got filtering and AA cranked all the way up and turn the film grain amount completely down.

Do you guys still think it's worth attempting an OC of the CPU?

The only thing that I've noticed now after rebooting a couple times (and I forgot this happened earlier) is that after installing that new video card, I get the windows hardware installation box that pops up each time i reboot and when i click cancel to find suitable drivers it says that it failed to install UAA audio something or other.

At first I dismissed it because it was audio but now i realized that this is a new box popping up and has only happened after I installed the card. I have no sound card, it's integrated so I'm not sure wtf the deal is with that.

Thoughts?

Edit: What about the fact that I'm running a PCIe2.0 card in a PCIe slot? I know they're backwards compatible but is it possible the bus attached to this slot can't handle what the card is trying to pump through it? If this question didn't already put it out there, I don't know a whole lot about mobo's and FSB or if there are other buses, etc
