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

Or is this maybe just a display driver issue? Is the rendering choppy also when you disable interpolation?

Thanks for your reply, Peter - the cache settings are equivalent across both processors. I am using SDRAM with the P4 (on an Asus P$ mainboard), if it makes any difference.

When I disable interpolation, the jagged edges occur in some images which are sized down to the display resolution (1024x768), but no artifacts, etc. are evident.

Are there libraries or settings from past PMView installs which may affect the rendering engine? This system is using the latest ATI All-in-One Radeon drivers for Windows 2000.

Thanks,
