Indepth comparison between P3D V2.5 and V3

[ErichB 3,643]

I can't wait to see this tonight.  Sounds interesting.

To a prospective user, thanks that was honestly nicer than I thought.

 

I see Jordan's rig is a monster though and it's still silly how low the FPS are with those addons.  On final (in between the stutters) they were avg 16 just eyeballing it.  On my rig I'd get about 12 lol.  Pathetic.  I guess we're still far from 30 fps locked in this scenario.  Obviously I note his very high settings (and AI traffic!), but default clouds/weather.  Also I do note this video is kinda a worse case addon scenario... as Orbx NCA crushes VAS (and my performance even with the crane deletions).

 

I was actually surprised on the VAS...  It appears in the VAS monster scenarios is where v3 shines.  For the first part of the film the vas was only 300MB lower but as he got nearer to SFO the difference was clear and the VAS optimizations made really clear as it stretched to 500-600MB.

Yes, that was also what surprised me most about his video: how performance on his monster rig dropped near the end. We still have a long way to go...

Two things though: fps always drops with video capture running. I'm sure fps would have been a good bit higher without it. I'm running v3 on a sub 4 ghz rig and it is much smoother.

 

Also, I get the impression he is running other background programs to put the video together--particularly the side-by-side shots.

Excellent video and guide. I hope Rob does not mind if I pin this topic.

 

Best regards,

Not at all Jim, I've been meaning to do a similar comparisons video, but just haven't been able to make time ... barely had time to scrape up those videos I did make ... glad someone else took the time to do it.

 

Still haven't got my http://www.p3dwiki.com populated with information, settings, etc. ... but plan to work on it this weekend.

 

Cheers, Rob.

I'm surprised you haven't gotten the wiki site up yet.  Seems like you have had plenty of time to do it in between your real life job in the KSFO area (and fighting traffic), your moderating duties here at AVSIM, some moderating at LM and your beta testing there for upgrades, and making several videos to show off a new feature or new addon for just released for P3D.  Oh!  And sometimes you respond with lengthy responses to members who are having issues and comment to topics in other forums here at AVSIM.  Then I think you are married too and you have those duties as well as I recall you race cars too.  I think you need to budget your time better so you can get the wiki site completed soon. :smile:

Enjoyed that video,  great insight into V3

That's a great overview of the new P3D v3.0 features.

 

I've done some testing myself yesterday comparing performance and VAS usage between 3.0 and 2.5 with this result:

 

 

My understanding of the behavior in the video is that P3D v3.0 only loads scenery that it needs therefore the VAS usage is much lower but it also means that it needs to do more scenery loading in-flight. When moving slowly at airports P3D v3.0 has higher FPS, but over extreemly crowded scenery FPS is a bit lower than P3D v2.5.

More loading - DeFrag your disk   OR  use SSD....

:Shame On You:

Both 2.5 and 3.0 are fully running on SSD. I'm just making an assumption that because 3.0 loads 600MB less VAS objects, it only seems to load objects when it needs them. Therefore 3.0 loads up scenarios more quickly. On the other hand 2.5 preloads a ton of object that it may or may not use, but when it does need them they have already been preloaded whereas 3.0 will always need to load new objects that it hasn't used yet.

Those crashes in the first video are a concern...he mentioned 2 PC crashes in the first 24 hours and that's before even installing most add-ons. Even my my trusty old FSX is more reliable than that would imply.

 

Regardless, will be purchasing P3Dv3 in the coming days/weeks. Can't resist.

Nice video, appreciate the effort!

 

But I still dislike the fact that scenery "pops" in as it get loaded. I would like to the feature in newer games where scenery is slowly loaded/faded into the game as you approach it.

I think he said it was when he tried to use GSX. Likely a conflict with GSX more than an issue with P3D, which is to be expected.

I was confused by that. In Jordans video everything loads smoothly on the horizon, in Bakas video things pop and look terrible. I think its something to do with their hardware or config.

Regarding video capture, it depends on what software/hardware you use. I've found virtually no drop in performance (on 2.5) using nvidia ShadowPlay.

Very nice vid.

 

So if one is satisfied with v2.5 and has everything set in a way that OOM's do not appear than v2.5 looks better than v3 as far as I can see from the vids.

In v3 scenery is jumping in , while in v2.5 it comes gradually.
