games laggy with dual core.

Games really need a combination of a good video card AND cpu to play properly even if you have a high end CPU. They both work hand in hand with each other. You will also need to have a minimum of 2GB of RAM, especially if you are running Vista, 4GB recommended.

What video card are you using? Try getting an 8800GTS 320MB...it's expensive but worth it if you are a gamer. Good luck!

done a defrag as well as all other clean ups i could do to try to free up resources. as for the system its an amd64x2 4400 on vista 32. 2 gigs of ram. geforce 7600gt vid card but ive only got onboard sound so that may be an issue but i dont think its to bad of one. the thing is i can run brand new games fine. dark messiah runs well (probably at 75% full settings) as well as oblivian. hl2 runs perfect and i know thats more of a system drag than painkiller. even at the lowest of setting on painkiller is crazy slow and jerky. ive uninstalled and reinstalled it with no luck. if i play it on my old juihb 1700 running at 2.0 ghz on xp with an old ti force card it works fine. im gonna try roling back some drivers to see if that helps but im not expecting too.

look and see if your antivirus program is running a scan. if not that then make sure ur firewall is allowing bf2 access. if neither of those check out then maybe ur internet connection is too slow for bf2 or it could just be the servers ur trying to play on.

Heres the rub, i bet the games will run fine under XP with the same system. Graphicsa card drivers for Vista are buggy. DX10 is still new, and is buggy. Vista is definately buggy, and games themselves are going to be buggy on vista. The platform is still so new that everyone is killing themselves to try and make their stuff work right, its a process that is going to take time. Dual boot XP if possible, and use it for gaming untill a DX10 title you absolutely must play comes out for Vista, then worry about the performance issues at that point, because by the time Crysis comes out I garuntee the performance of Vista, DX10, and graphics card drivers will be much better.

disabling onboard audio really helped me run bf2. install a pci soundcard and it will free the processor from rendering audio.

also make sure that your ram is running at specified speeds, b/c most motherboards downclock ram, but you can go into the bios and fix that real quick, that could help a little

I dual booted xp/vista earlier this summer and i wouldnt recommend it.

thanks for the tip mcg, inever tried that. im not sure i can in vista but ill look.

First off cool and quiet doesnt run on vist-yep bf2 has xfi problems and is memory sensitive but sound like dj_pee_zee
is right. Sounds like most likely ya graphics card-and yep would recogmend a 8800gts 320 but they run real hot so make sure ya case is up for that. Mine runs BF2 at 1600x1200 with no probs at 60-100 fps.

Cool and Quiet is supported in Vista without the need for the AMD driver (that was for XP). If it's not functioning, then it's either disabled in the BIOS or the BIOS needs updating.

Maby he didnt do it right,I have dual boot and love it.
Only games on gonna play on Vista are DX10 ones.
For those of you who are curious about what we are talking about,I will try to explain in plain english.
Dual boot mean to have 2 operating systen installed on the same computer.
Here is the quick non technical,plain english which I googled and did it myself.
You first have to partition your drive or just have 2 drives.
You must have XP installed first,then get the the OEM version of Vista or full version,but not the upgrade version.
Pop in Vista and it will ask you if you want to replace or create in available drive space,choose create.
Once installed in that manner avery time you boot up you'll get a choice of XP or Vista...WALLA no more compatability issues.

Edited - didn't see the OP had already downloaded the dual core optimizer.

how do you, set up a dual boot? (never actually tried myself), I assume you just set up a partiition and have one OS on each half

Definintly don't run games on Vista (or ME 2 as we refer to it) but set it up as dual boot. I set it up useing the "upgrade" for Vista and it works fine the only thing you have to make sure you do is on the first screen that asks what type of install make sure you specify a "clean" install; it will ask for your "old" windows disk (i showed it my 98 disk) then put Vista back in and it installed fine in my "D" partition. I don't know if i'm missing anything by doing it this way but I only wanted an install of Vista on one of my machines so I could play with it (so far I have to say it's a bit of a love hate thing) but it does allow you to test hardware and software to find out what does or does'nt work.

Don't recomend a dual boot? Why would you not recommend it? Personaly, I run a triple boot (XP-Pro32, XP-Pro x64, and Vista Ultimate 32) and I have no problems what so ever. I've been dual booting since 98/XP. If it's done right you don't have any problems what so ever.

Yeah, when a friend says "I've been having a problem with Windows" and you ask "which version of Windows?"

There's always that reaction when their reply is "Windows Me:"

Urrrgh!

I think you got the same problem as mine, I upgraded to dual core and didn't reinstall windows, and after that the game became choppy. So I reinstall windows, and game was smooth till I installed audio card driver!! I was rather mad and did some search, turns out that some games are not designed with dual core in mind, and depend on some cpu timer for game progress, and because it is dual core and windows switches cores during game play, the game will have 2 different timings and the display will be mess up.

The temp fix I had (I DON'T play that game often) is, once game starts up, open task manager, select that game process and right click, set Affinety to 1 core, and problem solved :-)
