(I couldn't find a Support forum, so I'll post my issue here. Sorry if this is not the right place.)
I installed GTAIV a month ago, but the game isn't running well, and I can't find any solution for my problem.
With the default graphic settings, I get 20 fps average during day, 16 fps at night and about 10 fps when it rains. But the real problem is that after some minutes of gameplay, the game starts lagging, it goes real slow and then freezes, with the background sound/music still going. I can't do anything else except reset my machine.
I've already lowered my graphic settings several times without any luck, both resolution and detail levels. I've searched around forums, and tested some possible solutions, but none worked for me.
Here is my full system specifications:
CPU: Intel C2Q Q6600 (no OC)
Motherboard: Gigabyte P35-DQ6
RAM: 4GB Corsair XMS2-6400C5
HDD: 2 x WD Raptor-X 150Gb - Raid_0
VGA: Sapphire ATi Radeon HD4850 512Mb (replaced)
Sound Card: Audigy 2 ZS
OS: Windows 7 Ultimate x64 RC
Can it be Windows 7 causing this issues? I know the OS recommend is either Vista SP1 or XP SP3, but Windows 7 is almost out, and I already pre-ordered one.
I've already sent a support request to Rockstar Games, but I haven't got any answer from them, and it has already passed 3 weeks.
After I tried those possible solutions I replaced my graphic card (Sapphire ATi Radeon HD4850 512Mb) with a Palit GeForce GTX 260 Sonic 216 SP 896 MB. The overall graphics have improved a lot, so has the viewing distance detail. But the game is still lagging and freezing.
I've noticed that when the game starts freezing, the HDD activity is very high. Is it possible that this game has compatibility issues with Raid_0?
Is anyone else having troubles with the PC version?
Do you have any suggestions for me?
