Interpolation slower from Pentium3 -> 4 Options

[Guest_Anonymous_*]

Hi Peter,
I've recently upgraded my Windows 2000 Professional system from a

> Pentium 3-500MHz with 512MB of RAM

to

> Pentium 4-1.5GHz with 1.5GB of RAM

and noticed that interpolation of larger images has slowed drastically. I have tried upgrading to the latest version (v2.31), to no avail - interpolation under the supposedly slower system was smooth and faster.

Under the Pentium 4 system, PMView interpolates larger images in a choppy manner, and is at least a magnitude slower to complete the render.

Any ideas?

Thanks,

- Wade

Are you sure that you're not running in 256 color mode? (Interpolation is much slower in 256 color mode since a nearest color search must be done for each pixel).

Check that you're using a video mode with deep color (15 bits or more).

Let's hope this is it. At least this would explain why it is significantly slower
