Nvidia Geforce 8800gt + Intel Dual-Core 2.6ghz performance issues??

[Shubham Kukreti]

Hello,
I got a 8800gt (upgraded from 9400gt)...My system specs
Intel Dual-Core 2.6ghz
2gb DDR3 RAM
Nvidia GeForce 8800gt 512mb
Western Digital 320gb HDD
450w PSU....
Earlier with my 9400gt,performance in Battlefield BC2 was alright at 1024x768 everything on low and I got 60fps..But now in my 8800gt at 1024x768 low I am getting 30fps....I have tried everything and every setting but i cannot get more than 30fps.I maxed out the game and still got 30fps,I know that my 8800gt can perform better but it is not and I cannot figure why.
The same situtation is there in Hitman;Absolution,Homefront,Just Cause 2,AC3 etc.....In these games I cannot get more than 30fps at even the lowest possible settings,and 30fps too at the highest settings.....PLS HELP..And the main problem is that the fps do not change a bit even if I change the settings.....
I have updated all the drivers and BIOS.Still no change.

Maybe your PSU don't have enough juice to run the 8800GT, the card requires 26A on the +12V rails. You need to shut down your PC and open the side panel and check the sticker on the PSU.

it sounds like a v-synch issue to me, and it is locking itself at 30fps.

have you re-installed the drivers after changing cards, as you really should, I had to between a 8800 gtx and gtx470

Yes I have reinstalled the drivers,infact I formatted my system to reduce errors but still no change.

Hey according to the sticker on my PSU,MAX VOLTAGE +5V and MAX CURRENT 25A..Does the performance of the gpu depend upon the power supply????
Do I need to change my PSU and I yes then please recommend a new one...Thanks

Sorry, I don't understand "MAX VOLTAGE +5V" - all PSUs have +12V outputs, can you please post what you see in the columns under +3.3V, +5v, +12V ?

This is what I found on the sticker of my PSU
VOLTAGE CURRENT
+5V 25A
-5V .5A
+12V 10A
-12V .5A
-3.3V 14A
+5VSB 1.5A

Are you sure there only one 12V rail, and not two like +12V1, +12V2? Because that is very low output, and for your system you need 26A on the 12V rails. If 10A is what you got you will need a new PSU. It is better for the PC to get a branded model, it is worth the price. For your system I recommend the Corsair 450VX.

OK...I will upgrade it..Does the performance of the GPU depend upon power???

Yes, if the GPU doesn't get enough power from the 12V rails it will not operate properly.

Hey got the PSU recommended by you,still no change.

Use the software GPU-Z to check if your PCIe slot runs all full speed (x16).

The Bus Interface is PCI-E 2.0 x16 @ 16 1.1

Is there a chance of bottlenecking in my pc????
And today I tried FIFA 11
1600x900
HIGH Settings
MSAA 4x
V Sync- ON
And I got 60+FPS....

 

[13thmonkey]

there is always bottlenecking

 

[Shubham Kukreti]

there is always bottlenecking

So what should I do now???? Because some games are running fine but some are not..

You got a balanced PC with the 2.66GHz C2D CPU and the 8800GT, with any better GPU your CPU will become a bottleneck, you have chosen well.
There could be also an issue with your RAM amount, If you have Vista or Win 7 or Win 8 it is recommended to have 4GB.

I looked at the system reqrirements of the games mentioned, most of the games listed on your first post require 2GB of RAM as minimum and 3-4GB for recommended settings, but FIFA 11 require just 1GB as minimum and 2GB. Check if you are getting better performance with games that require less RAM, is so, you will need more.

Ok i will get additional 2gb ram for my pc.....Actually you are right I tried COD 4,COD 5 they too are running at MAX settings with 70+FPS(They also require 2gb ram).In Assassins Creed 3 my game started lagging in Boston...Other wise in Ship level i was getting 50+FPs...

But GTA 4 sucks
800x600
Lowest Possible Settings.
Draw Distance etc all are set to 1
STILL AVG. FPS=25
MAX FPS=35

GTA 4 is a bad console port, and you will need a quad core CPU@ 3GHz and a GPU like the GTX 460 with 1GB VRAM to run this game at medium-high settings.

And what about AC3 and Max Payne 3???

These games are relatively new and quite heavy for your PC, but you should get better performance than GTA4 at lowest settings (with 4GB RAM).
