GTA IV Performance Issues?

Blue Pixel · March 30, 2013

Recently bought the GTA IV bundle from Steam and thought that with my GTX 660 Ti and my i5 3550 I should be able to run it without to much of an issue at 1080p. I was wrong.

Put all the setting up to their highest except for the Traffic Density, View Distance and Detail Distance and was getting around 30fps with 99% GPU load. Turned the shadows down to high as this is usually the thing that cripples my FPS and it was. GPU load went down to around 50 - 60% with a steady 60fps (V-Synch is on) but was till getting drops down to 40fps but with no change in the GPU load so it must be my CPU.

Anyone know what the main CPU hog is on GTA IV or any background tweaks I can make?

My aim is to get a solid 60fps with very few fps dips but I don't want to have to lower all my settings too much.

Thanks

7870 and i5 3570k here my gpu load used to be 40% when i had shadows on medium and my fps was 40-60, then i turned all shadows to max almost same fps vehicle density was also always on 75% but lowering didnt change pretty much anything but still it was around 40-60fps i even installed iCEnhancer mod which im loving and still same fps which means my computer can run it properly but it isn't optimized at all.

i have a 3770k and a gtx560 and play maxed except from view distance and get fps raped to like 10fps when driving fast disable vsync its a killer for fps only need it when you can keep a steady 60fps all the time in game

It's a notoriously bad console port. I'd get dips below 30fps on a gtx 570 + i5 2500k. Your best bet is just to tone down the shadows and view distances.

If you lower the shadows it doesn't utilize your gpu at all and puts more strain on your cpu.

For me shadows on Very High uses 99% GPU load and around 30 - 40fps. Turn them down to High and GPU decreases to around 60% with a mostly steady 60fps. The reason I have V-Synch on is for the most part it is a steady 60fps but I do get occasional dips to ~50fps mark.

I shouldn't really be complaining as it is a solid 60fps for 80% of the time/ I just wondering if anyone knew any little tricks to improve performance.
