A few comments:
- You should not use normal combiner and normal blender no matter what, because you don't have to use them.
- You should not use TNT combiner if your driver is newer than 41.09 because it won't work.
- You should use 2-stage combiner for your GF2 MX if the driver version is newer than 41.09, but it won't give you good result anyway because there are only 2 stages. It is normal, no suprise.
- Frame buffer features seem not working on GFFX5600.
