Under pure DOS enable LFB and MTRR and use 32bpp depth if you have such VESA mode. When program exit it display last frame render time it can give you idea if changed setting led to change in performance. With LFB and set MTTRs I got ~20ms in 1600x1200/32bpp. But don't expect the same speed as your windows use HW 2D acceleration. I simply redraw entire screen everytime you scroll (+-10 pixels).

I know, it need to fix Y-offset when zoom or goto another page. Will be fixed.

No on first load I must specify some DPI but I don't know anything about image yet. When 1st page loads I can read image resolution and then adjust DPI for best fit. Yes I can do this calculation before start drawing on screen, see next update...

BTW there's short help if you press F1
