I now met a guy in a german hardware-forum having the exact same problem only with playing World of Warcraft ....
Here are his specs (in german):

Asus Mobo P5N-D mit einem Intel Core 2 Quad Q6600 Prozessor(2,4GHz), 4GB DDR2 800 Ram, 750Watt Netzteil mit 4* 12V 20A + halt der Restversorgung und einer Samsung 500GB 7200Umin, 16MB Cache Sata2 Festplatte. Betriebsystem ist Win XP 32Bit.

it's not bottlenecking. his cpu is a quadcore inel. i have a duel core phenom running a GTX470 and i don't suffer these problems. the only difference is i'm on windows 7 and the op is on windows xp.

so bottleneckin seems out of the picture for now ....

what else can we look into ??????????????

it may seem a bit extreme but if you have a spare hard drive around i would try installing windows on there with just the necessaries such as graphics drivers, chipset drivers etc, install lfs and try that. Sometimes all they need is a windows reinstall

:-)

imma be away for almost a week now sadly but will do so after my return ...
... hoping somebody comes up with something else till then

(checkin in here every once in a while)

Thank all you guys for being helpful here!!!!!!

give this site a go: http://extreme.outervision.com/psucalculatorlite.jsp if you have any usb connected, add them too. this will tell you how much power you will be using.
this is mine:
System Type: 1 physical CPU
Motherboard: Regular - Desktop
CPU: AMD Phenom II X2 550 3100 MHz Callisto
CPU Utilization (TDP): 90% TDP

RAM: 4 Sticks DDR2 SDRAM
Video Card: NVIDIA GeForce GTX 470
Video Type: Single Card

IDE HDD 5400 rpm: 1 HDD
Regular SATA: 2 HDDs
Green SATA: 1 HDD

DVD-RW/DVD+RW Drive: 1 Drive

Sound Blaster - All Models: Yes

USB: 2 Devices

Fans
Regular: 1 Fan 250mm;
LED: 3 Fans 140mm;
High Performance: 3 Fans 140mm;

Keyboard and mouse: Yes

System Load: 90 %



Recommended Wattage: 523 Watts

if you have a pci sound card, just select soundblaster as i have.

just did mine (had to go with gtx 465 since 460 is not listed) :


System Type:
1 physical CPU
Motherboard:
Regular - Desktop
CPU:
AMD Athlon 64 X2 5000+ EE 2600 MHz AM2 Brisbane
CPU Utilization (TDP):
90% TDP

SCSI HDD 7200 rpm:

PCI TV Tuner - Cable:
Yes

USB:

Fans

Regular:
2 Fans 120mm;

Cold Cathodes:
1 Cathode

Keyboard and mouse:
Yes

System Load:
90 %


Recommended Wattage:
436 Watts

remember, that's at 90% load. at 100% load, you'd be closer to 500watts.

What an annoying problem has me stumped, might be just a bad driver set or maybe the ati chipset just isn't playing nice with the nvidia drivers?

All the psu makers seem to be using the same calc now.

Hey guys,

i am back still not makin any progress :-(

Anything u guys can advice me to try ????

thx

I just installed my new 460. If you still on your 500w PSU try a better one, i guess. I am running a 550w coolermaster and it seems to be fine...

Other then that, only thing i do is using tweakforce nvidia drivers, although i doubt that it would make much of a difference in your case, but they seem to be always great (besides they are much 'lighter')

PS. just for my interest, which is your manufactor (mine gigabyte) and did you need to plug 2 power cables in?

I still am on 500W PSU. I read a lot of comments regarding latency problems with this card ....

My gtx is a Gainward GS

the tweakforce drivers did not make a difference.

318is

I get the exact same problem,

After changing my 7600GT due to it failing, I upgraded to a 460 GTX

Where the 7600GT would do 66 fps on a corner
The 460 GTX does 28 fps (which is un playable)


The 460 GTX also installed Nvidia HD audio drivers which are causing DPC Latency issues with my Sound Blaster X-Fi Xtreme Audio (something NVIDIA are aware of)


Looking for suggestions too

can u please give more details to your system and maybe what you tried so far (like new installation or such)

what psu you use for example?

really hoping this can be solved soon!!!!

Intel Duel Core 6300
4x DDR2 512 533mhz ram (2gb)
1x PCI-e Sound Blaster X-Fi Xtreme Audio
Gigabyte Motherboard
Corsair TX 650w
3x USBs
PS2 Keyboard
USB Mouse
Palit Nvidia 460 GTX
XP SP3 OS
2x SATA2 HDDS

As a note:
Test drive unlimited on all high settings works perfect
Battlefield 2 on all high settings works perfect
CSS - Counterstrike stress test hits 139fps


I can limit LFS to lowest settings and = 28fps (LFS car parked @ said corner)
I can then set LFS to max video settings = same 28fps
Core 1 CPU = 80% use @ 28fps corner "when moving" never gets above 80% peak
Core 2 CPU = 10% use @ 28fps corner "when moving" never gets above 20% peak


- Does LFS support 1gb cards?
- Does win xp sp3 support 1gb cards?
- The 460 GTX also installed Nvidia HD audio drivers which are causing DPC Latency issues with my Sound Blaster X-Fi Xtreme Audio (something NVIDIA are aware of)

Thanks

my 470 has 1.25GB and runs fine. i did buy a 720watt psu too to make sure i had more than enough power for my system.

<-- XP SP3, 460gtx 1gb

Did you guys mod LFS somehow? SO, full grid, onboard last car, i have 55fps.

No mods at all

Simple remove the 7600GT and swap to a 460 GTX


I take it LFS doesnt support something on the new card?

I tried a brand new lfs "installation" without any mods - same problem ....

uninstall old driver, reboot, install new driver, reboot.
even though you had a 7600GT, it's best to remove any driver/software linked to the old hardware. then reboot and install the new hardware.

I had a "clean" system to start with - same problem .....

My brother has identical psu(500 watt seasonic with 2 17A rails) and graphics card(gainward golden sample 460) and he has no issues at all so as i said before i would try a clean windows install but thats just me, doing what dadge said should fix it too unless something is faulty in your system.

If you put the old card back in does it run fine again?

I started with no nvidia drivers on the system and cleaned all graphics drivers from the system as explained earlier in the thread (cleaner tool).

With the old card I have no problems - neither do I have problems with the onboard graphics card.

wildboy99 = what version of windows is he running ?
318is = did you see your pm and try it ?
JazzOn = are you ok to do a test with me on a track? (ill park side by side with you?)

Quote from Daviddabest :

JazzOn = are you ok to do a test with me on a track? (ill park side by side with you?)

Tomorrow afternoon maybe, but i'm running a E8400 (3ghz). So that might have quite an influence.. somewhat. I'll be online or on the forum
