how to make Gran Tursimo 4 playable?

[Boosted23]

hello there

first i want to say, i have read this thread about GT4, but it didnt really help me.

first off, my system.

CPU: phenom x3 2.8 ghz
ram: 4 GB
GPU: radeon HD 4850 512 mb
OS: win 7 64 bit

it does start, but with some problems.
its the NTSC version.
im having lines on the screen, missing letters, artefacts on the screen, the other thread said put 480p and it should work.
but for me it doesnt

second problem is the game speed.
sometimes it runs at about the half of the normal speed, sometimes twice as fast, or even faster.

third problem is, that i cant race at all.
as soon as i start a race/license test psx2 crashes.

ive tried the mentioned fixes, but they didnt help me
im using version 0.9.4, is there a more stable version to play on?
or is it all about the right settings?

would be thankful if any of u guys have some answers for me

im using version 0.9.4

Dude, that version is ancient.
Grab the latest beta and plugin pack from here.

[Boosted23]

ok...so i got the beta and applied the fixes mentioned, race also starts, but now i have the problem that my whole screen is full of huge pixels only the speedo is clearly visible.

ideas?

DX is the latest.

Im not sure what you mean. Low resolution?
If so try and increase the internal resolution in gsdx settings. Do note that increasing this causes much more load on your graphic card, and if it cant handle it the game will slowdown, it can also cause in minor artifacts in some cases.

[Boosted23]

no, its not the resolution.
the whole screen is full of artefacts, u can only see colors, but not the track or cars.

Ok I see. Unfortunatly I have had no experience with this game my self so I have no idea about this specific problem. Try software mode in gsdx if that solves it there is probably that much you can do as software will be very slow. If thats not it then someone else who have dealt with this before might be able to help more.

What's your plugin configuration ? Screenshots will help.

[Boosted23]

i actually got it as i looked through that other thread again.
only the low fps are killing it now...ranges from 25 to 55 most of the time...
tried pretty much all the speedhacks already, but nothing helps...looks like ill have to wait till psx2 will be more optimized, or till i have a new cpu

You need to set brightness to 0 in game.
