just resize your browser window

if you want precise window size, use chrome, get extension called Window Resizer and set the viewport resolution with any resolution you want (you can run KanColle in independent window so your browsing activity won't be bothered by small window size if you use chrome for browsing too). I believe KanColle run natively at 800x480 pixel.

I managed to decrease CPU usage and my KanColle run nicely and without lag and stutter in my 6 years old laptop. If I play with the game stretched, it always stutter in battle sequence.

but if you prefer the stretched version, well, that's your choice
