Gran Turismo 4

[ingliz83]

I am trying to run Gran Turismo 4 on my PC

I am using the original BIOS from my mates PS2

My PC specs are:

Core i7 920 C0 @ 2.8GHz

12GB DDR3 1333Mhz RAM

Nvidia GTX 560 OC

Win 7 64Bit fully updated

However when i try to do any lisences my in-game screen becomes all pixelled and the game slows down incredibly...

Does anyone know how to get this working on a system like mine please?

There are dozens of threads about this. The easiest solution is setting the in game brightness to 0, but don't expect to get full speed with this game with just 2.8 Ghz.

At least my GT4 works fine without changing the brightness.

That is also known as piracy, you must own the ps2 you are using the BIOS from, anything else is considered illegal and wont be supported here.
