Interpolation slower from Pentium3 -> 4 Options Track this topic Email this topic Print this topic Download this topic Subscribe to this forum Display Modes Outline Switch to: Standard Switch to: Linear+

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,

Peter, good suggestion, but I'm definitely running in 32bit color mode at 1024x768.

Again, it's only when the image is larger than my display resolution that the interpolation is noticeably slow. Very odd, especially since the graphics benchmarks seem to indicate no issues with the Ati card. I suppose this is somehow related to how PMView is working with my 1.5GHz P4 processor, but even though I'm using SDRAM on this Asus P4 motherboard, things shouldn't be slower than under my 600MHz P3 on a P2B motherboard.

I'm stumped.
