There isn’t a glow filter (not realy). There is a second plane with a mixed alpha to simulate a glow. And yes I tried the 2D-Filter version of Zaghaghi but it doesn’t seem to work in combination with self created GLSL-Filters. Must be a problem in that way the shaders are setted. So if you use your own shader it will be overwritten by the 2D-Filter(Shader).
By the way: There seems to be a bug in the blenderplayer. If I try to save it as a runtime
it always crashes as well as I drag the blend file over the blenderplayer.exe that comes with the original version of Blender 2.45. If I drag the same file over the blenderplayer.exe done by Zaghaghi it works.
I got 17 fps on an AMD Sempron 2800+ with a gForce 6100 chipset onboard (128 MB shared)
1 GB RAM
and 28 fps on an AMD X2 4800 with a gForce 7300 graphics board with 512 MB
2 GB RAM
