Help. Geforce 9600 GT Win7 = terrible performance.

That's the link you are using?

Also, have you updated your bios to F6?

Download GPU-Z.. Make sure your card is running at x16..

Hello!!!!!!!!!

My system is as follows,

Windows 7 64bit
Gigabyte M720-US3
Phenom 2 945
2gb corsair XMS2 DDR2 800mhz
Display driver 195.62

I'm getting really bad graphics performance. I lost like 10 FPS on RE5 benchmark versus windows XP 32bit. On Left 4 dead 2 my average FPS is around 35-45, and even lower if I turn shader quality up to maximum (which the game recommends)

On my old system (AMD 3800 X2 Win XP) I never got any slow down on L4D 1 and there isn't much difference between the 2 games graphically.

I ran SiSoft Sandra GPU benchmarks and my GT 9600 scored quite a bit lower then the reference cards.

My memory and CPU clock are both at stock.

Is this a driver problem? What can I do to improve things, please?

You see what I made bold? You see the difference? Just as the main RAM is 2x the size, the data on the GPU ram is 2x the size... So do you understand a performance loss with double the registers? Yeah it affects all aspects of the system. Now also I'm going to say the 9600 GT series was a huge letdown, given the fact that some of the 8xxx series cards performed better....that and the fact that the 8800/9800 are the same card..... I'm going to say the that being 64 bit might be part of the issue, as my card has problems with higher textures even though it's rated for them. Though on a 32bit system it runs quicker. =)

No the 2G main memory is fine, that's what I'm using. But 512 128bit memory on the gfx card isn't enough for the gfx processing. 650/1500 core/shader is fine.... But if your using 64bit the 128bit RAM (I'm just guessing your running a 9600 that has 512 with 128bit DDR3?) doesn't have the speeds required to move the data as fast as it would on 32bit.... This is NOT related to your 2G main ram, as it has plenty of space for running the games... I can run COD4 MW2 with 2G just fine, I had 1G and it ran pretty smooth. Although I am running DDR3 at 833 dual chan... So a ram upgrade wouldn't be a bad idea, though a better GFX card would be ideal for 64bit.

The clocks are not fine - 64 shaders? Precisely why I bought a 4890 - for the price 800 shaders and a core of 850MHz is enough for today's games. Lucky that card has a 256-bit memory bus, although GDDR3 is being replaced by GDDR5.

Dude, I'm running an 8800GT at 625/1625/922 speeds and I can play every game out to date max quality. The only thing I lack is the transfer speeds for high res pictures, so higher resolutions won't work as well... this is also due to my 512MB ram on my card.... Do you want screenshots? No? The speeds for the GeF275 aren't even as high as the 850MHz you have for your ATi, it's how they do the architecture as well. Maybe I should start getting my refrences posted, but I've been doing this bs since The voodoo's and I know how the speeds affect the FPS in new games. Infact the core clock isn't even the big one, it's the shader clock that really makes the fps boost.... But on top of that what's the #1 kicker for performance? RAM speeds and interface! Oh yeah, the 256 > 128 ect ect... And the lower end cards have 96-128 and I'm betting his is 128.... Oh wait, here let me get you specs for the G275

Code:

                     XFX GX260XADJC GeForce GTX 260 896MB 448-bit DDR3 PCI Express 2.0  x16 HDCP Ready SLI Support Video Card - Retail                     



Chipset Manufacturer: NVIDIA
Core Clock:  576MHz
Shader Clock: 1296MHz
Memory Clock:  2000MHz

Oh you see that bold? YOu see the ram interface? My 8800GT has higher clock/shader than this bad boy but probably sucks **** compared to it.... Why? BECAUSE OF WHAT I SAID EARLIER!!! ATi has over spec'd **** because they don't do the card's arch as nice as NV. It's just how ****'s been for a long time.

[edit] Oh my bad, that's the 260, oh wait that's STILL newer than both our cards.

[seccond edit]

• Stream Processors: 216 Processor Cores

Oh I forgot it has twice the stream processors as my 8800GT but that doesn't do much on low res pictures, as I get 60+ fps on any game max quality with all options on.... Even Stalker COP works fine.... Oh but you probably figured that out already.

Switch back to 32bit and see how that goes?

[edit] Err I mean try Win7 32bit.
