The performance scalability of scripts in XySubFilter confuses me. I have two essentially equivalent scripts:

The first script executes with nearly zero overhead as measured by CPU load. The second one uses 100% CPU on fullscreen (2560x1600) and causes massive stuttering. Looking at the tags, I can't see any obvious reason one would be slower than the other. If anything, the first one should be slower since it uses a wider blur and has a secondary layer.
