I’m rendering some quite large polygon who are for the most part transparent (alpha=0), say 50-80% of their area. (And one polygon covers around 10 % of the screen)
What are the general guidelines for getting good performance? (This is on GeForce-class cards). I have three options:
- Clip the polygons to save fillrate.
- Use AlphaTest to save bandwidth.
- Leave it as it is, as above options slow things down too much.
I haven’t done any benchmarks yet, but I figured some of you guys probably know about this.
I’m mostly curious on whether enabling alpha test in this case is good conduct or not.
