Quick Question- Is there anyway to speed- up 2D Filter Sys?

Is there anyway to speed- up 2D Filter System?
Martinsh did a great job creating those amazing 2D filters but having a Focus 2D filter, a HDR and RETINEX …really slows the game down.
So that’s all I am asking.

You can try to make your own Filters, which would use less Samples – for example.

No real chance to speed this up at shader level.

Just reduce resolution, but this have to be done at bge 2d filter core. Moguri mentioned already some good ideas for improving this system.

Thanks!
That would require some advanced modifications to blender, bad thing.
Smaller res would do the job.
