hi i have messed around with point sprites yesterday and to my disappointment i realized that their scaling behaviour doesn t really fit to my particle engine my particles shall not resize with growing/decreasing distance from the viewer so i did some research but no answers whether it is possible to keep the size with point sprites i am for 25000 particles in my engine( you really don t need more then 25000) well 25000 visible + x times as many in the list now i have found some topics about using triangles and applying a texture to them to lower the amount of vertex manipulation so should i use triangles instead of quads or pointsprites or do you have any other suggestions? i am going to use vertex arrays btw sort particles by texture do the vertex manipulations and place them in the right order into the vertex array and then simply draw them thus i get rid of invisible particles and unnecessarry function calls to avoid function call overhead any suggestions? thx in advance

i inlines all the rendering routines inside the engine that increase the FPS rate a lot
and i use lots of static variables and access arrays via pointers and not [xyz]
