I know, i remember having my 60GB PS3 (about 6 -7 years ago) where i mostly played GT4 on, this was before GT5 and my goal was to complete it before release, after the first demo for GT Academy i nearly gave up playing it, the worst thing was that i was at the end of the GT World Championship, a few days later my PS3 gets a
YLOD , but still i look back now, it is much easier for me to play GT4 when i run it on my PC, i play it in 1080p, a greater resolution to GT5 (but still not better graphics) now the game is much easier for me, and if i could i would dominate the GT World Championship.
Here's some footage of my PC running GT4 in 1080p
This is a video i made of LasVegas in GT4 with cheats.

In the video there seems to be borders which block your entrance to the end of the course, the version in GT4 Prologue seems to be the same but a change in the map design. In this version you are capable of going to the other side of the course.
