Alright, I lied. This is a typical FPS complaint thread. My GTA WAS fine, but now it's not playable at all.
No, seriously. Completely unplayable.
When I first started up GTA IV on my PC, I was getting completely ridiculous lag, even on the in-game menu screen. 1.5 FPS on a good day. I solved this issue somehow, and ended up being able to run the game on maximum settings at 25 FPS (This was about a year ago).Problem is, I've now patched my game, everything has been reset, I don't remember how I fixed it last time, so I'm stuck, back in the slums of Lagsville.
I have tried everything. Restart upon restart with different things changed. Things I've tried:
- Reverting to previous patch: Tried. Nope.
- GPU Settings: I've gone to my NVIDIA Control Panel and turned all the settings to lowest for GTA IV.
- GameBooster: Barely noticable difference.
- Graphics/Display settings: I have tried having them on highest, medium and lowest. Nothing.
- Background programs/processes: I know that GameBooster does this but I double checked anyway. Still nothing.
I ran three benchmark tests, first one using high(est) settings, then medium, and finally low(est) and these were my results:
Average FPS: 1.39
Duration: 45.18 sec
CPU Usage: 21%
System memory usage: 58%
Video memory usage: 46%
Video Mode: 1280 x 1024 (60 Hz)
Texture Quality: High
Render Quality: High
View Distance: 30
Detail Distance: 50
Average FPS: 1.86
Duration: 8.59 sec
CPU Usage: 18%
System memory usage: 54%
Video memory usage: 31%
Video Mode: 1280 x 720 (60 Hz)
Texture Quality: Medium
Render Quality: Medium
View Distance: 15
Detail Distance: 20
Average FPS: 1.82
Duration: 10.46 sec
CPU Usage: 20%
System memory usage: 51%
Video memory usage: 19%
Video Mode: 800 x 600 (60 Hz)
Texture Quality: Low
Render Quality: Low
View Distance: 1
Detail Distance: 1
My System Specs are as follows:
Microsoft Windows 7 Home Premium SP1 (64-Bit)
GPU: NVIDIA GeForce GT 430
Video Driver version: 331.65
Audio Adapter: Speakers (VIA High Definition Audio)
AMD Athlon II Quad Core X4 640 Processor (3.00GHz)
As you can see, my system is more than capable of running the game, and it was doing so, perfectly fine, until I patched it. barely ANY difference in FPS between the three. Now, here's the thing. In all of the benchmarks, I can see that the CPU usage never exceeds 21%. Surely that's not right? Isn't GTA IV so poorly optimised it's basically on a high-carb CPU diet? Surely it should be eating up my CPU like nothing else? This leads me to think that my cute little GeForce GT 430 is trying to be a little soldier and handle the processing all by itself, which obviously is a bad idea on such a small card. If that is the case, then could someone please tell me how to make the game use more of the CPU rather than my GPU?
If that isn't the problem, and it's something else completely, then my ears (well, eyes) are open, and I'm willing to listen to whatever you guys/girls(?) think the problem could be.
Any help would be very much appreciated, and I'll be very grateful for your assistance. I know I'm a mug for not remembering what I did last time to fix it, but I've exhausted what I can from Google, so I'm pretty sure it wasn't something blindingly obvious. I really do miss popping old ladies kneecaps while riding a motorbike so getting this fixed is my main priority at the moment.
Thanks in advance,
