"Is this because it was badly ported or something else?"

Short answer..............Yes.

GTAIV is a very bad console port and has never worked properly. Low FPS is just one of many problems with the release.

Don't worry about it. It has nothing to do with your PC. Just move onto a new game.

Oh sorry,

ATi RADEON HD 6970/6950 I can't remember which.

Also, power is no problem, there is a 1200w in it.

no cpu is not limiting gpu the cpu is good so is the gpu.
but there are no cpu's who can keep up with video cards so there will be limitations in ur case those limitations are very very rare to occur.
eventhough there is enough power in it post ur psu specs.
and what games are u playing, what settings although u should max most modern games and get about 50-60fps easily

The one I'm most concerned with is GTA4 (the gfx resource hog) When I run max settings I get 22-30 fps. However, if I lower the settings, no difference in fps. The res is 1440x900. Is this because it was badly ported or something else?

Something is wrong, first use GPUz to check if the video card bus interface(it should be PCI-E x16@x16).
Do u have latest video card driver?

also check the temps in gpu-z and check the clocks if they are in full throttle.
check gpu load if its 90-99

How do I check if it's running at 16x? Also, I don't really want to overclock if that's what you mean, Toxic.

EDIT: I think I got the whole 16x thing. It's running at 4x :/ I think I need to rearrange my case and move my hard drives.

U have found the problem. Video card isn't getting enough power to run it a full speed. a bad power cord or bad pci-e power cable can cause pci-e x16@x4 problem. Try to reset them.

PCI-E x16 slot is created specially for video cards.
Now the performance is OK?

Actually no... It's the same, trying it on different games to test, except that's the only one that really tests it other than Metro 2033 with DX11. All cables are fine, I checked when I rearranged my case.

EDIT: DX10 Crysis runs fine.

If other games runs ok, there's something wrong with driver or GTA IV.

"GTAIV is a very bad console port and has never worked properly. Low FPS is just one of many problems with the release"
It's a bad port (not very bad port).

"Just move onto a new game"
Not a good advice, u don't run away from a problem.

"Not a good advice, u don't run away from a problem."

OK, I'll bite.

Better advice is to spend more time trying to play a "Very Bad" port of a 4 year old game? I've had this particular game since release and played it (or attempted to) on my last 3 builds. It ain't worth it. A quck Google search will show you it is littered with problems.

If RafeZweigun want's to play, he can try turning down the draw distance, fully patch the game and use latest graphics drivers to get better FPS.

My opinion is, his time is better spent elsewhere.

I would like to point out that I needed to go back one update because the new drivers crashed and GTA4 is kept up to date by Steam.
