Hi all,

Any help would be really appreciated as im quite distressed about this issue.
I saved up and purchased an LG 4k monitor for my mac to run the programme on, it replaces a really old 1080p monitor which worked fine but was just...old.

When playing back my projects (and demo projects) the video is hugely jerky- almost as if it were missing frames or something. When exported the movie looks fine, and not jerkiness- but its meaning that  I can't work on the project itself due to this framerate issue

For reference i'm using and LG 27UL850  and a mac mini (same mac mini that works fine with my much older monitor)

Any ideas? I thought maybe it has something to do with freesync on these modern monitors but turning it off made no difference.
I've tried plugging into my mac via USBC/Thunderbolt and HDMI and no difference. Is there a hidden setting in CTA somewhere perhaps?

Hi...

Running Cartoon Animator 4 at ultra high resolutions like 4K puts a greater strain on your computer than running at standard HD resolutions. This sadly means that will get a slower frame rate as a result. On really powerful computers the drop in frame rate may be very small but on less powerful computers you will get a noticeable drop in performance as you have found.

You can try going into Preferences (CTRL+P) > Render settings and lower the "Max Real-time Map Size" to improve performance but overall unless you plan on getting a more powerful computer you may be better running at 1920 x 1080 which is recommended for less powerful computers.
