wonder if it works any quicker then before?

My main complain has always been is that FF renders things pretty slowly and rather non-interactive, Curious if they did any essential advancement in that field since version 3?

I have to say that one of the main reason I do not keep working with Filter Forge, is that the render speed are mostly slow, unless you make simple photographic effects or use images lower than 2000 or 3000 pixels

Please, see the Vladimir quote below and the links below

As far as I know from the tests I have done, FF 4.0 is slightly faster and depending on what filter you use you could get a little more benefit, but in general not much.

In my personal opinion, I feel bad that this software is really great, awesome, amazing and you can make really stunning, lovely and wonderful things, and now there are 10804 filters, BUT the main and most important problem, is and has been always the RENDER SPEED on higher resolutions than 3000x3000.

There is no news that I know that this going to change in FF 5.0 that would be a very bad thing that FF 5.0 would keep the same render engine

I have a great fear that FF will be loosing much against other software companies and the evolution of software

I FEAR Filter Forge be in danger of loosing market and be left behind

And I do not want that could happen something bad to FF company

Will FF sink like Titanic when crashes against the competition Iceberg

Vladimir wrote this and the below quote in 2012 and I wonder if something may have change in these nearly 3 YEARS.

VLADIMIR GOLOVIN WROTE ON July 2012 Quote Please, I want to know if the FF Inc. is working on the development of a optimized and better render engine that could process the filters faster than what is available in FF 3.0. Alas, the situation on this front hasn't changed much. The most viable way to speed up the renderer at this point would be to rewrite it to use a GPU-supporting architecture, but the existing codebase is built around the CPU paradigm, so a straight port is extremely difficult. I posted about this before. We experimented with GPUs, observed insane gains in performance on some tasks, but we decided not to pursue this approach. Basically it would mean rewriting the renderer from scratch, plus we'd likely encounter big, really big problems with backward compatibility. If we started writing Filter Forge today, or a couple of years ago, we'd certainly build it to utilize GPUs. This would also work for a separate product that doesn't have to maintain compatibility with Filter Forge (that is, being able to render its filters from all versions down to v 1.0).
