@ripu: you shouldn't be so hard on yourself, mistakes happen. :)

Ignore my previous comment. I am an idiot. It actually uses an old version of Sumatra, which was faster and lighter.

I was using sumatra for a long time. Recently I had to open a high graphics magagine PDF. And it was very slow, slower than foxit and pdfxchange. Then I tried all the pdf viewers in this site.

After testing I found that, Universal Viewer is the fastest PDF viewer, especially for high graphics magagine kind of PDFs. I have a lower mid range laptop. Universal viewer throws sumatra, pdfxcange, foxit out of water when it comes to speed of loading one after another high graphics page. And it's the lightest of all the PDF viewers, uses minimal CPU unlike others I have mentioned.

Any ideas if the portable browser plugin still works with v3.x? When I follow SYSTEM's extraction instructions above, I don't get npPdfViewer.dll but two other dlls, PdfFilter and PdfPreview. Without nPdfViewer the plugin does not work, with it opera:plugins (good ole Opera 12) says the plugin is still at v2.5.2, the version of said dll.

SumatraPDF would be great if it didn't support DRM. It prevents you from copying or printing PDFs that are "protected", and the author refuses to make it optional. Hypocritical for Free Software to support DRM if you ask me.
