   Point sprite size
  My point sprite seems to get smaller as I move the camera closer to the points, and I don't understand why :SMy camera class is just a simple matrix which I load first (whith the inverse translation and rotation of the camera in), which the other objects multiplies with later.Here you can see the unwanted result: http://spurv.net/point.png   
  are u sure theyre getting smaller?perhaps theyre staying the same screensize (but since the onscreen distance between the particles is larger they look like going smaller)for such small number of particles, Ill recommend not using pointsprites, they have a number of issues   ;  Could be that they just stay in the same screen coordinate size, yes.I thought a particle system would gain a large benefit (in fps) from using point sprite insted of billboarded quads? Maybe I'll look into how to do it with shaders :O   ;  with most PS's the performance hit comes from the drawing (usually u have blending enabled etc) + the vertex vs pixel size is normally quite low. + not the processing of vertexsthe only reason u would want to use pointsprites is if youre drawing lots >10,000 of very small particleseven if u had 100 torchs Ild still recommend not using them
