- postpawl 7y agoiTerm2 started doing some GPU rendering stuff in version 3.2 (https://iterm2.com/downloads/stable/iTerm2-3_2_0.changelog https://iterm2.com/downloads/stable/iTerm2-3_2_0.changelog). Maybe it's faster since you last used it?
- sudofail 7y agoI just double checked and Alacritty is indeed much faster still. This issue is probably the single most important feature for me in a terminal emulator, and unfortunately iTerm2 just doesn't cut it yet. On my 5k display, at full screen resolution, iTerm2 scrolls in a large vim buffer at max 40fps. Alacritty on the other hand is around 60fps. Not sure how to enable an FPS meter on the Terminal app, but it feels closer to 10-15fps. I used iTerm2 for years, and am still a Patron, but until GPU acceleration gets to 60fps at 5k resolution, I don't think I'll be switching back. It's still one of my favorite open source projects, and is only one of two that I currently pay for each month. So I sincerely recommend it to anyone who doesn't care too much about terminal performance.
