"Contrails" not showing?

[Gaalnr]

Those little contrails that you get when you are going fast and jumping at the same time arn't showing up for me, but I see other people streaming jet set radio HD on the PC and they do have the contrails. Anyone else have this problem? Is there a way to fix it?

[Gaalnr]

just a little update on what I have found; if I put the game in 720p (I usally run it in 1080p) then the contrails will work fine. Who knows why or what I can do to fix it in 1080p, but there ya go.

Its a resolution issue, like you found. the textures are stored in a shared .PVR image in an obscure ratio. Huge resolutions (and this is blits fault, everything is still in dc format. (you can probably play it on dc)) overwrite transparency values in the engine making them fully transparent, and for the most part, not appear at the right coordinates on the player. at the most, the will be mapped INSIDE the player model, you cannot see them.
