Bugs and Glitches

Audio Popping

Regardless of the SFX Volume and Music Volume settings there will be some short audio pops that play at full volume sporadically while driving. These sounds originate from the Sound Manager; patching out the Sound Manager update function makes them, and every other sound, stop playing. The game thinks it is playing these sounds at the correct volume as the DisplaySoundInfo command shows the user selected volume for all of the sounds it displays. It is likely that they are being configured using a different interface than the rest of the sounds; one that does not set the Direct Sound buffer volume to be the same as the game's internal sound structure volume in the Sound Manager's update function. They are created and played with the same interface as the rest of the sounds so the bug must originate in proximity to creation when the game's internal sound structure is configured. Hooking the IDirectSound::CreateSoundBuffer method and setting the volume to DSBVOLUME_MIN before handing the buffer handle back to the game successfully eliminates the popping. This is proof that the game is never setting the volume of these buffers.

No VSync

The EnableVSYnc command appears to have no effect on the actual VSync setting.

Weird FPS Locking Behavior

When launching the game with DisableMOvie so that the intro video is never played, the framerate will be locked ~65 fps. After enabling movies again and playing one, the framerate will be unlocked.

Weird Driver Model Pose On Spawn

Sometimes when the driver respawns after a crash, the mount points will be in the right place but the other parts of the mesh will be in weird positions. This bug appears to go away when the fps is locked to 60.

Alt-Tab Unload Behavior

When alt-tabing out of the game in full screen mode, all world objects will unload and slowly load back in when the window gains focus. This has the side effect of disabling collision with most things while the game is minimized.

Alt-Tab Soft Lock

If you alt-tab fast enough the screen will go black and lock until the process is killed.

Camp Menu Text Replacement When Exiting With GFWL

DirectInput Support Is Broken

Only the XInput support is fully functional.

Ghost Barn

One of the barn meshes doesn't have collision.

Invisible/Disappearing FUEL Barrels

Sometimes the FUEL Barrels will disappear while on screen.

Memory Leaks

Performance decreases dramatically as the game runs and memory usage increases.

Collision Crash

The game will crash during a physics collision very rarely. Although if you play for a long enough time it will happen eventually. It can also happen only 1-2 hours into playing.

Tree Missing Face

One of the "ramp trees" is missing a face on the underside of the ramp part.

Respawn in Ground

If a respawn point is recorded on a steep slope and you are oriented perpendicular to the slope, there is a chance you will respawn with half of the vehicle embedded in the slope.

Flickering

I don't think this is related to fps. Looks like really fast scanlines. Most noticeable in snowy areas.

Transparent Terrain

Sometimes when returning from Alt-Tab certain models like trees will be visible through the terrain.

Invisible Bush

There's a bush that has collision but no model.
