Westrock Posted December 4, 2006 Share Posted December 4, 2006 Whenever I'm editing larger pictures (like 1800x1200 and up) when I use the Lasso to add to a selection its pretty slow, but when I take away a selection its pretty quick. When I draw the initial selection with the Lasso its very quick. This is on both my laptop and my main computer. My Laptop I can understand (1.8Ghz Turion64). My main computer is a AMD X2 4600 and if I bring up Task Manager while Lasso is sitting there updating the CPU Utilization only hits like 50% and really one of them is running at like 60%, and the other is maybe 10%-20%. Memory is 1.5Gb DDR2. Heres a screenshot to show. Down by the bottom is where it was still drawning the line while I had time to bring up Task Manager and hit PRNT SCRN. Is this normal behavior, due to the way the selection works or something? Link to comment Share on other sites More sharing options...
Rick Brewster Posted December 4, 2006 Share Posted December 4, 2006 The code for selection union and exclusion is just brute-force and slow. We know of a more sophisticated algorithm which makes this enormously faster, but the implementation is extremely complicated and difficult which is why I haven't yet finished or integrated it.

Westrock Posted December 4, 2006 Author Share Posted December 4, 2006 OK, I just wanted to make sure everything was OK on my end. It just seems like it use to be a little faster back when I was using 2.x. Link to comment Share on other sites More sharing options...
Rick Brewster Posted December 4, 2006 Share Posted December 4, 2006 Yeah everything is fine on your end. A lot of code has changed in version 3.0 so I wouldn't be surprised if rendering performance is randomly up or down by a few percent.

brun0 Posted October 2, 2009 Share Posted October 2, 2009 Sorry for digging such an old thread but I don´t want to create another one just to ask whether it´s going to be improved in v4 (I hope so :wink: ). Link to comment Share on other sites More sharing options...
Onemorelevel Posted October 2, 2009 Share Posted October 2, 2009 Read the rules. 11) Don't reply to very old threads. Also known as "reviving" or "resusitating" old/dead threads. Also called "necroposting" (eww). If there has been no discussion in a thread for, say, 3 months ... then it is dead. Do not reply to it -- pretend like it is locked. If you reply to it, then the thread will be immediately locked and your post may be deleted. Please just create a new thread if you have something to say about that subject. However, this rule does not apply to The Overflow, Tutorials, Pictorium, or Plugins sections of the forum. Saying sorry isnt going to help. This thread is nearly 3 years old.

Rick Brewster Posted October 2, 2009 Share Posted October 2, 2009 But the problem is persisting. It doesn't matter. Necroposting like this is against the rules, not to mention disrespectful.
