[GTA IV LAGG] I need your help!

[Matthew Jones]

Hello people of Tom's Hardware!

I bought a new Graphics card for my computer, I installed it and it worked. It runs alot of games flawlessly so I know that it isn't the problem (E.g It runs Skyrim on Ultra and Arma 2 on Very High),

But when I go to run GTA IV It plays perfectly fine for around 10-15 seconds on 60 fps then it drops down to 3-10 fps. I tried turning all the settings down but to no avail. With everything on Low, Shadows off, VSync off and all of the sliders to 1 (for view distance ect) but the same problem occurs.

Can anyone help?

Here are my specs:

AMD A85600k APU
nVidia GTX 760 SC (Super Charged) 2GB GDDR5 Ram
650w PSU
8GB DDR3 Ram

I know it's not the spec of the pc that is the problem, can anyone please help?

Thanks.

Check your temps, the APU should not be more then 74C, the GPU keep it below 80C. To me it sounds like the CPU is down clocking from heat.

GTA IV is a very Power Hungry Game & was a Rushed Badly optimized port, Although still my favorite game of all time. I Think Viking is right that something is getting too hot. I originally played this in late 2008 on a Q6600 & XFX 9800GTX+ & it ran smooth. With my Current system I had to add a bottom fan to blow over the Videocard & VRM's & it solved my Problem.
