fullscreen[browser]

'Fit image to window' has a slight delay of about 0.5 secs on my PC before filling the screen with the high quality enlarged image--and I have an very fast CPU. I'm fitting 1024x768 images onto 1600x1200 screen size. Zoom-in and zoom-out works performs instantly and doesn't have this delay. Is it possible to make 'fit image to window' happen instantly? Perhaps make image fill screen instantly [in low quality first] then apply high quality redraw?

V 1.90 RC1

I have the same delay with zoom and fit, perhaps could you use 'option/fullscree/use delay'?

good to know, thanks. but is it possible to make 'fit image to window' work instantly like high quality zoom-in/out? perhaps optimize the process a bit?

But for me 'fit image to window' work like high quality zoom-in/out

so the only thing that would help is to get even faster CPU?

Yes, this is due to the HQ resize algorithm being rather slow. It's only fast with zoom because HQ isn't applied there in the fullscreen - if you try it with view mode, watch as it gets unbearably slow as you resize from 100% to 800%.

It is most likely possible to optimize it, but I don't think that's a priority. (It would be fastest to use the graphics card, which has hardware bilinear, but I'm sure that's not easy.) If "read ahead" at some point includes the resized version, then I think it will become a moot point anyway.

(GIF animations suffer some crazy slowdowns with HQ fullscreen, probably because frames aren't queued at all. Cool effect, but ultimately too slow. ;_; )

Good summary. Another suggestion has also been made. All this has already been suggested elsewhere (this thread could be 'closed').

Might be worth disabling HQ with animated GIF for 1.90, then...
