In the new version, everything is redesigned, and the graphics became more realistic. Now it will not lag, on processors intel core 2 duo graphics goes under 30-40 fps, And you do not need a powerful computer. The graphics are not very bright, besides it can be adjusted, I advise playing either at medium brightness or at maximum brightness.
Installation: everything from the MOD folder (which is in the archive) is moved to the GTA 4. directory!
