|---|---|---|
| zgreg | unity's dash blur is still a bit slow for me | 22:08 |
| zgreg | I have taken a look at the blur shaders, and it does a *huge* amount of texture lookups | 22:08 |
| zgreg | IIRC it does 29 lookups to process a single pixel for both vertical and horizontal filtering, so in total almost 60 lookups for one output pixel! | 22:09 |
| zgreg | this seems kind of insane... | 22:10 |
| zgreg | also, I noticed there's a more efficient blur implementation in nux already | 22:10 |
| zgreg | it uses linear sampling to reduce the number of needed texture lookups | 22:10 |
| zgreg | why is this not used? | 22:11 |
