Welcome to TVPaint Community forums !

I'm not sure that this is a technical issue or just my machine letting me down but when I installed the 8.5 upgrade the brushes seemed to be slower.

My main concern is a 100 pix airbrush I have been using for an ongoing project. To get the speed I was used to in the old version I have had to turn off 'sub pixel' in the preferences.

In fact to be honest all the brushes now seem 'laggy' with sub pixel on

Anyone else noticed this?

Same here...

Maybe it's because I have a new computer with the fast xeon processors, but I don't experience any problems with the speed of the brushes.
Actually they even improved, because before this update I had problems with a pencil that made sharp angles instead of circles when drawing fast.
That problem is over now.

Even with the sub pixel off I'm getting straight lines when I start drawing with the new pencils.

On what machine are you running the app ? Pc or Mac ?
If you're running it on a Mac, check the OpenGL option which can cause the app to run slower than usual with certain configuration (although performances are improved on some other configuration).
You'll find that checkbox in the Preference panel.
It might be checked by default and unchecking it can fix the problem.

Feel free to let us know if it solves the problem, thanks.

No. I'm running a PC which seemed to run the previous version OK.

P4 3.2, 2gig memory, Nvidia 6600 (256) winXP (sp2)

Running the 8.5 demo and finding the same thing, pretty much identical specs to MrChoy.

This is just a wild guess.. Could there be a problem with nvidia cards? I found some problems with both, pc and mac and both have nvidia cards.

i have nvidia also. (PC)

I don't have this kind of problem here (PC with a NVIDIA 7600GT GFX card)
