Note: I've already asked this question, but it was later at night, therefore I didn't get as many answers. I'm asking again to see what other answers I can get before giving up on my problem.


To start off I have a few mods installed. They are ELS, LCPDFR, a few police cars, a 1977 Trans Am, a dune buggy, and Icenhancer. Before I installed Icenhancer, I was getting around 40 FPS on average (which caught me off guard for a 2008 game, with my setup) so, I thought I'd continue installing my mods. I installed Icenhancer, and I was still around the 35-40 FPS range, I figured that Icenhancer would drop my frames down to at least 30 fps, but it didn't. I hoped that my system could max this game and maintain 50-60+ FPS. If I reduce ANY of the settings, I still get 35-40 FPS. In an uncrowded area, such as a beach, I get around or above 60 FPS. The weird thing is, is that my CPU sits around 60-70% usage, and my gpu sits around 80-90% usage, meaning its not utilizing my system to the fullest, so I should be getting better framerates than 35-40. Please help.

PC Specs:

CPU: Intel Core i5-4670K @ 3.4GHz
CPU Cooler: Cooler Master Hyper 212 EVO

Video Card: MSI GeForce GTX 770 2GB Video Card
Case: NZXT Phantom 530 (Black) ATX Full Tower Case

It's because the 2gb of vram is being full and the GPU needs to take RAM Form the system RAM. System RAM is usually clocked at 1600mhz and the vram oft your GTX 770 is clocked at 6000mhz.
This can cause a lot of stutter

My GPU ram usage sits at 50-60%, don't see how that could be the cause. And I'm running at 1366x768, because I have not purchased a 1080p monitor yet. So I don't think that could be the cause.

Maybe it's your CPU bottlenecking in that game, because mods will let the CPU do all the work for the mods and it can't feed the GTX 770. Try checking GPU and CPU usage

Did you read my original post?

And I'm pretty sure a 4670k wouldn't bottleneck a GTX 770.

Yeah it's an bottleneck there. when the GPU and the CPU aren't both at 100 or minimum 90 % of usage, there is an bottleneck

It's cause GTA IV was coded by dead monkeys who really don't understand PC gaming in any way at all. Game runs terribly on nearly any setup and there is pretty much nothing you can do about it.

Here are some command line codes that you can try but I didn't find that they helped much.

Why would you create a 2nd thread, if the first one was already answered ?

ERm... not sure what is radekmm going on about.

That game is horribly optimized or rather not optimized for PC at all. It doesn't work that well at all even on more powerful machines.

It's not your PC, it's the game.

@radekmm Did you read any of the original post? Or just the title and specs? Plus most of the things you are saying are plain wrong.
