what kind of gpu and cpu do you recommend to max it out? It is wierd because i see many videos of gta 4 that show max setting with a gtx 460 1gb but since I overclocked my gtx 460 768mb it should be performing better than 1gb one..
Do you think my cpu is possibly making the game run slow?
Does gta 4 require at least quad core for the max setting?
You have 8 less ROPs, and much less memory bandwidth. You would have to OC by a lot more then what the 1GB card has to make up for this. I also wouldn't say you have a tri core just like the 360 so your fine. Remember that the 360 is highly optimized with its OS and the game, and doesn't need to take into consideration the differences that can be found on the PC. Most people will say you need a highly clocked quad core AND a big GPU. Try OCing your CPU and see if/how that helps.
and I am getting a horrible FPS when i play gta 4. (Around 13 fps) When i max it out.
So i set it to medium high graphic and it is still 20 to 24 fps in average.
What could be causing the game to get so low FPS? It is kinda wierd because I get 40 to 50 FPS maxed out in similar games such as Mafia 2 which has better graphic
Unfortunately, Cutebeans is right. GTA IV is highly unoptimized. I've played it on several high-end PCs over the years and never been able to run at MAX setting with an acceptable frame rate. Hell, now I'm running a Phenom II 955 quad-core (OC'd to 3.8), Radeon 6950 1GB, 8GB of RAM, and I can't get what I'd consider acceptable FPS on less than MAX settings. Running everything on HIGH, with 8X anisotropic filtering, and no AA (not supported by game engine) I get between 25 and 35 fps while driving, and maybe 40-50 fps when on foot. The only rig I've seen able to run it at 60fps at HIGH or VERY HIGH settings was a Crossfire setup with a pair of 6950s. So, if you just have to get a silky frame rate on GTA IV, plan on picking up another 460 and going SLI.
I think the problem is with your CPU. Even though it's tri-core, I don't think it's sufficient to run GTA 4. However, I have an entry-level gaming system which has a poor CPU but can run GTA 4.
Here is my setup:
4GB 1333mhz Single Channel RAM
And yet, I can play GTA 4 at 1080p max settings, 45-60 FPS
*I would suggest that you update your GTA 4 to the latest patch.
