uuderzo Posted October 17, 2008 Report Share Posted October 17, 2008 Igor,does this option affect performance or prefetching times?Thanks. Umberto Quote Link to comment Share on other sites More sharing options...
Igor Posted October 17, 2008 Author Report Share Posted October 17, 2008 It's free. Just resulting image looks a little more soft.

uuderzo Posted October 21, 2008 Report Share Posted October 21, 2008 Trying this option I noticed that the animation "jumps" when the mipmapped picture comes in.Maybe due to the time needed to compute mipmaps?Umberto.It's free.

Lin Evans Posted October 21, 2008 Report Share Posted October 21, 2008 Hi Umberto,This probably indicates a marginal video card or low resources - on seven different systems we run I have never seen an instance of this happening.Best regards,Lin Quote Link to comment Share on other sites More sharing options...
Igor Posted October 22, 2008 Author Report Share Posted October 22, 2008 Umberto,Trying this option I noticed that the animation "jumps" when the mipmapped picture comes in. Maybe due to the time needed to compute mipmaps?You are right! Really images with enabled "Mipmapping" option were not created and pre-loaded in advance. We just fixed this bug. Please wait for Beta 4. Probably it's main reason of jumps in animation you've found (if you slides contains objects with enabled "Mip-mapping..." option).

uuderzo Posted October 22, 2008 Report Share Posted October 22, 2008 Igor, thank you for replying. I sent you a PM about the difference between mipmapping problem and "jump after fade" problem (or better: "acceleration after fade" problem)Regards, Umberto.Umberto,You are right!

Igor Posted October 22, 2008 Author Report Share Posted October 22, 2008 Umberto,We just fixed this bug with mipmapping, please try updated beta:http://www.wnsoft.com/test/apr-deluxe_beta_fix.zipp.s. we didn't change anything for "acceleration after fade" problem yet.

uuderzo Posted October 22, 2008 Report Share Posted October 22, 2008 I can try the new beta this evening.I don't have my laptop with me now.Please be patient. Thank you, UmbertoUmberto,We just fixed this bug with mipmapping, please try updated beta:http://www.wnsoft.com/test/apr-deluxe_beta_fix.zipp.s. we didn't change anything for "acceleration after fade" problem yet.

Adda Posted October 22, 2008 Report Share Posted October 22, 2008 Ups, with Beta 4 I have more jerking than with Beta 3.If I deactivate Mip-mapping in all slides I have less jerking and it plays quite smooth also with my old GeForce 6600 GT card.Andreas Quote Link to comment Share on other sites More sharing options...
uuderzo Posted October 22, 2008 Report Share Posted October 22, 2008 Igor,Just performed some testing on b4.The freeze before mipmapped picture comes in is still here, but it's less noticeable.I must say that the show I use as test performs continuous panning and zooming instarting and ending slides, maybe this prevents the mipmapping "builder" to takeenough time to prepare all the mipmaps.Obviously, if the first slide remains still before the mipmapped image comes in,there is no freeze at all, well, maybe there is but it's not visible.Anyway, personally I think that mipmapping is not so big trouble since I think i'll livewithout it if my machine cannot support it well.On the countrary, the "acceleration after fade" effect does concern me a lot, sinceit is not avoidable. It looks like the new algorithm performs some kind of averagingon previous frames time renderings, maybe with the purpose of smoothing theadaption to different frame rates... but this has the effect that a fast frame rate changeneeds about 1 second to be readjusted. It's really noticeable.Maybe on faster machines the frame rate does not change too much between fadeand after fade (two pictures and one single picture) but I suspect that this should benoticed also on faster GPUs.I wait some good new on this aspect Regards, Umberto.Umberto,We just fixed this bug with mipmapping, please try updated beta:http://www.wnsoft.com/test/apr-deluxe_beta_fix.zipp.s. we didn't change anything for "acceleration after fade" problem yet.

Igor Posted October 28, 2008 Author Report Share Posted October 28, 2008 Umberto,We just reworked mipmapping option and it should work much better when mipmapping enabled. I'm sure it will fix the problem you've described. Please try Beta 5 when it's done. Quote Link to comment Share on other sites More sharing options...
uuderzo Posted November 3, 2008 Report Share Posted November 3, 2008 Igor,Finally I did some test with 5.6b6.I confirm that the mipmapping "pre computing" glitches are gone.It works well also on my machine (geeh!)I confirm you also that when Aero Glass is turned on the animation has less frames per second but it is more stable,without strange accelerations after fadings.When Aero Glass is turned off the animation is more fluid but in some points of the show there are thoseannoying accelerations, and that makes me think that I'll keep using PTE with Aero Glass despite the lower performance.It looks like the bad effect comes in after fading from an heavy slide (with heavy I mean 4 or 5 pictures animated with Ken Burns effects).Fading simple Ken Burns effects between single pictures does not introduce those effects.I'll try when possible to install also XP on this machine and see what changes.Regards.
