Hi Bash and Slash.. people. I'm new here and I have a problem with MW2. And CoD4. I've had this problem for quite some time (two months or so). As long as I've played CoD4 or MW2 on my new computer basically. Maybe you know of this issue?

What the problem is:
When playing online I get this issue where the game jerks briefly every 3-5 seconds. The game in general is pretty laggy and I can get killed AFTER reaching cover (not through the wall I mean). When watching killcam I see myself shooting at places where people WERE. Ping is always excellent. FPS is good. This problem varies in severity.

Difference from problem in CoD4:
It is usually A LOT worse in big or demanding maps like highrise, rundown, favellas (I actually get bad FPS on those too).

Do you recognize this issue? Let me know what you know.



More info:

What I've ruled out, what's NOT causing it (probably):
- The installation: It happens in both mw1 and mw2 and I reinstalled mw1 several times.
- Punkbuster: MW2 doesn't use it and I've disabled it from running in the background.
- The Router: I've tried with the one here and the one at my dad's house. Also without.
- The Switch: I've removed it from my network config; problem remains.
- Audio Hardware Acceleration: Has been turned off.
- Graphic Settings: My computer can render it alright. I get 100 fps+ and singleplayer is fine.
- Network Cable: I have changed my network cable.
- Network Card: I've put a D-link network card in to replace built-in realtek one.
- Friends Overlay: I've disabled steam overlay for MW2 and didn't run MW1 with steam.
- Drivers: I’ve updated my video and audio card.

Current Suspects:
- ISP: I haven't noticed much in other games but maybe CoD-games work in a different way.
- Hardware: Maybe something is faulty; but what? And why only in multiplayer?
- OS Installation/Program Conflicts: There may be something installed on my computer that collides with MW2. I have no idea what.

Computer rig:
Gigabyte GA-MA790XT-UD4P Socket-AM3, Radeon XFX 4870 1gb xXx, Phenom II X4 940, 4gb Corsair Dominator

Please please please help! I put up with this issue for weeks, knowing that MW2 was around the corner and thinking, in my grand naivety, that MW2 would run perfectly. Really I thought it was punkbuster. And no, this hasn't got to do with lack of dedicated servers (which I know is a kick in the nuts). This is worse.

that red line in ur lag o meter is actually packet loss try increasing the amount of packet dup that u are using
/cl_packetdup # in cod4
seta cl_packetdup # in cod6(mw2)

The number was "1" in the config. I set it to 5. No difference I'm afraid.

try /cl_maxpackets 100

I tried that. Problem still remains

I'm borrowing a radeon 4890 and different memory from a friend later today. I'll run with that and see if it works...

Tried the 4890. No difference.
Is it just me that has bad performance on highrise, favelas, estate and rundown?

Runs 120% on all other maps. Smooth as hell (graphically, not always networkically).

You may also want to read this. I know it was written for Windows 7, but it works for Vista as well.

If you are on XP, then note that Compound TCP is only available for the 64-bit edition of Windows XP (which is actually just Server 2003 with "Windows XP" plastered all over it), and that if you are using the 32-bit version of Windows XP then you won't have Compound TCP available.

I almost hate to post that link though, as I know it's going to help Sanity reduce his latency as well... The last thing we need is Sanity running around with an even lower ping than he already has...

As you noticed earlier, I have the same issues, on only thoose maps. Totally weird, Its totally a config or a bug problem for our system, Cuz its not the hardware.

And i tried going directly to the broadband modem instead of the router inbetween, but it doesnt help...




Hope for a good cfg or for the retards to fix the game a bit.

Well, I think it's the game. But then again... too few people are complaining about it. We have quite good PC's.
Later today I'm going to install the game on my dad's computer which is worse then mine in every regard. If it's a performance issue it should reveal itself on his too.

As mentioned before, the only link between our systems is 4870 and Corsair PSU.
Gigabyte GA-MA790XT-UD4P Socket-AM3, Radeon XFX 4870 1gb xXx, Phenom II X4 940, 4gb Corsair Dominator, Corsair 550W, Seagate ES2
E8400 @ 3.0Ghz, Dualcore, 4gig ddr2 800mhz, Asus p5k/epu P35 motherboard, 400W Corsair , HD 4870 512mb ddr3

Depending on the age of your Corsair Power Supply it is actually in the risk zone of being too weak.

Change seta r_drawWater "1" |TO| seta r_drawWater "0" and it will be fine, Atleast it was like that for me.

And i know its on the weak side, but i wont have to replace it for like a year or something, Since its brand new:D
