Brush lag?!?

[EpicReator]

If i take a bigger brush size and work on a bigger canvas the brush have sometimes hard lags. Is there any option to fix this? In Photoshop this lag does not exist with big sizes. Maybe there is something with the systemconfiguration i can do with paintstorm?

Hairy brush is very demanding to processor (there is no hairy brush in Photoshop ) what about classic (stamp type) brush - more controlers(angle,size,opacity,brush form) - more lags. Round brush is fastest. Also if you are use custom brush form - be sure that it's not very large (some times users draw 500px brush with 2000px brush form - extreme lags) , also you can increase spacing for big brushes (photoshop default spacing is not zero)
