Okay, if we want a quality patch for GP4, we better go bug hunting ASAP. Chances are that the production of patches will stop after a couple of months if not weeks, so the more bugs we find now, the less we will be stuck with later.
When you report a bug, be as clear as possible on how it shows itself, how easy it is to reproduce and how this is done, and what the effects are, and if there is a workaround. If the tech dudes have to stumble around blindly in the code, or they can't reproduce the problem, chances are that it will be discarded in a cost/benefit analysis. So the better we work now, the higher the chances of getting the bug fixed.
Do not report bugs that come from any other version than the retail version of GP4. Warez are not only illegal, they often increase the amout of bugs in a game. Be sure that you have observed the bug in the retail version, and that all the details in the report comes from the retail version
Remember that bugs can be software/hardware specific. If the bug you report is not easy for others to reproduce, be ready to supply your system configuration, OS and driver and DirectX versions.
I will try to sum up, and update the list as often as necessary. But since there is no edit function on this board, it might take a while between the updates of the list.
Happy hunting!
Bug list draft version 1.00
-----------------------------
1) Right front wheel disappears at random both for player and AI cars. Physics do respond to the missing wheel. It does not happen very often. It can happen in any game mode at any location on the track, even during pit stops. Workaround: Activate the replay function. Rewind to before the wheel disappeared and play at normal rate, and the wheel returns both in the replay and in game. Hard to reproduce.
2) When to AI cars of the same team enter the pits with in seconds of each other, they become stuck in front of the garage. The pit crew does not come to collect the cars. Hence the are stuck forever. It happens in free practice, warmup, qualify. Observed at Nürburgring. No workaround. Hard to reproduce.
3) Sometimes the pit crew will not let player/AI car go from the pit stop. The car is stuck forever. Seems not to be related to any specific track. No workaround. Hard to reproduce.
4) If the car that your point of view starts in when you enter the track is going to have a mechanical failure, then the left yellow led on the steering wheel is activated on all cars. Hence the player always knows if he will have a failure. No workaround. Hard to reproduce.
5) The slider buttons on the 2 pit stop slider in the setup screen do not work properly. Workaround: Use the slider to decrease, and decrease button to increase. Very easy to reproduce.
6) There is no popup text help for launch control in the driving aids menu. No workaround. Very easy to reproduce.
7) Zooming in vertically on the traces in the telemetry menu produces a large grey box in the lower left corner of the screen. No workaround. Very easy to reproduce.
It's only after we've lost everything, that we are free to do anything.
