Preview Scaling - 270p

4K proxied clips playback smoothly with preview scaling at 360p, until there are effects, like Text, then it lags.

Can we please have a new setting of 270p plus a keyboard shortcut/hot key, say, of Shift F7?

Thank you.

Can you please share your computer specs? If your computer struggles to apply the text filter on a 540 proxy with 360 preview scaling, then I suspect it may fall below the minimum system requirements:

If it does meet the minimum system requirements, then there is something else going on which we should try to figure out. Maybe restart your computer or close other applications?
