Same problem, 2560x1600 display running Mountain Lion. Sublime text is pretty much unusable if I make the window as large as I can. If I halve the window, it's perfectly fast. This happens regardless of how much text is rendering, and having plugins or not makes no real difference to the speed. Really frustrating as everything else I use have no lag problems at all, is there any chance this will be fixed?

Hi,

I am new to this forum but thought I would put my five cents worth in regarding this problem. I echo the same issues just about everyone else in the thread has, when using the window at just over half of the screen (vertically) on a 24" monitor at a resolution of 1920 x 1080 the typing becomes extremely laggy, ianfitz video he posted demonstrates the exact issue I am having, I tried to take a look at what peppy posted but the dropbox link doesn't seem to be functioning anymore. Like others have also said in the thread when using "fullscreen mode" typing just becomes unbearable.

I am using the latest version of Sublime Text 2 on Mountain Lion (10.8, Mac Pro) with all software up to date. I have installed some packages within ST2 but from what people have reported this problem is evident in clean installs as well so I really don't see the point in removing what I have. I am a very big fan of ST2, I have found it to be an excellent editor after trying multiple others I wouldn't change. I do hope something in the form of a patch can be released to resolve this issue or some feedback on how to fix it because it is really annoying not being able to split screen my development.

I will be keeping a close eye on this thread to see how it goes, thanks for your time.

Giganic.

The latest nightly build (2218) made a huge difference for me, now it's perfectly acceptable on 2560x1600 mac pro with 8800 GT for me.

I'm not so sure the Nightly 2218 release has made that much of different in terms of performance, selection/GoTo.. is still really very laggy. I've hidden the miniMap as a few people have mentioned to do, to help with performance, but to no avail.. :(

HOWEVER, I just found a very interesting data point. If I resize my sublime text window to something really small like 300px x 400px, typing is crazy fast with no delay. If I then adjust the height from 400px to 500px, I notice a very slight but manageable delay if I type really really fast. If I boost the window height to 600px, now the delay is starting to get to the point where I occasionally notice it at normal typing speed. This curve continues, the point where if I make it full screen 1440x900, the slowness is as I describe in my original post.


Absolutely true.
Mac users. It's not Retina or MacBook problem. I have Debian on a simple machine with average 1280x1024 Dell and it's extremely slow.
I found this thread with Google search "sublime text too slow".
I tried standard package and dev tarball. Disabling code map and switching off all the code intelligence functions. There is no plugins. I tried it on a clean X server without Desktop Environment at all. All the same. Cursor is jumping "from word to word" like in Vim if you're moving from the beginning of the word to the next one.

BuyMeACola: The performance issues mentioned in this thread were specific to Retina displays on OS X, and have been resolved in the current nightly dev and nightly builds (builds 2218 and later).

In general, Linux performance has always been good, even at 2560x1600. Some users have encountered speed issues in Linux that were resolved with a display driver update. You may also want to check that your display is running in 24 bit or 32 bit color. Plugins can cause performance issues, so it's also worth following these instructions: http://www.sublimetext.com/docs/2/revert.html

I just downloaded the latest nightly build (2219) on my Retina Macbook Pro and the typing delay has been resolved except for the first line of a document. The rest of the lines are lightning quick.
