Xplane 10 64bit first experiments: DR400 over Paris

Featured Replies

Warning: X-plane 10.20 is in very early beta state. Do not download it, except if you'd really want to be a beta tester and know what it means. And if you do so, please read the release notes and the 64bit FAQ.

 

Disclaimer: Everyone interested in the subject should know it by now: X-Plane 64 does not run faster than the 32 bit version. It only allows people with powerful computers to push graphical settings higher, and make good use of all RAM and Video memory available.

 

I run X-Plane on Linux, and was often hit by the virtual memory limit crashes which plagues the 32bit version. Especially when flying over orthophotos covered with buildings extracted from OpenStreetMap with the great OSM2XP utility. For example, flying over Paris was impossible due to the sheer amount of building present in the OSM data.

 

So the first thing I did when testing the new beta was to put back the OSM scenery folder, and start at Orly with the beautiful DR400 from XPFR. And there I was, flying over Paris, playing with the settings until nearly everyting was maxed out.

 

(Technical details: Number of buildings: max.Trees: max or nearly max. Roads: max. Textures size: max. Shadows: max. World details distance: medium or high depending on the shot. HDR on. Antialiasing: 4xFSAA + FXAA.)

 

Ok this is not what I call flyable. Usually between 7 and 20 fps. And very soon my system started to swap a lot, which means it used every drop of my 8GB RAM. Ok ok, I'll buy more. ;)

 

But this is interesting anyway. I don't thinks I have ever seen that many objects in a sim. Correct me if I'm wrong. At least, this gives a good idea of what X-Plane will allow in the very near future in term of polygon number. I bought my GPU (Nv 680) half a year ago, I guess the next generation will have no problem at all displaying every single small house in Paris at a reasonable framerate. Right now, I just have to take two or three of the settings down one notch to enjoy a perfectly fluid flight. But I wanted to show you some more extreme shots. I find this totally crazy. And you ? What do you think ?

Very interesting to see, thank you.

My first reaction also was: Mon Dieu!

Should one blow the computing budget, or wait?

Hang on, this all sounds familiar...

I did the same, pretty much turned everything up.

 

HDR changes the equation a bit, though. :P

 

I enjoyed not having the system chugg as you pan across Ksea at full detail.

I noticed that with the same world distance details setting, HDR displays the buildings up to a much higher distance. In fact, only HDR prerendering coupled with instanciation can produce such results. And the new AA modes give excellent results, this was the main drawback with HDR and I think it's now solved.

I will fiddle with the AA a bit more, probably. I am just toying with the demo, right now.

Superb!

It looks amazing. One thing is for sure you will never ever see that much detail in FSX. Ever. Even if someone managed to make it 64bit somehow the autogen detail distance is hardcoded into the engine from what I understand and you would still get all the annoying "popping" of objects.

 

One thing I noticed in some of those pics though is that there are still a few areas that are too flat and lack detail i.e. some of the streets are lacking trees beside the road and there are some tree-park areas that don't seem to have any autogen. I'm sure this will only improve but was just something that I noticed.

You're absolutely right in your observation. Please note this is not X-Plane autogen. The buildings are X-plane "façades" (some kind of lego brick) built from OSM data by Benny's OSM2XP. Every building has a realistic projected shape, but the height and exact 3D shape is just a "plausible" deduction by some nifty algorythm. As you can imagine, the Eiffel tower's shape and height is all wrong. ;)

Yes, trees are lacking along the streets, that would give a still better look. Alpilotx released an add-on to add trees along the country roads. Maybe someone could do that for the city streets.

Wow that is impressive indeed. XP10 sure has alot of potential. The absence of popping is a major advantage vs FSX.

Great shots ! :Applause:

 

I'm now beta-testing the 64-bit version of a famous regional jet for X-Plane, and it's just awesome.

 

Pascal, if you want trees near roads, there's of course the AlpilotX solution:

There's also another solution: OSM2XP (again), but you first need to contribute to OpenStreetMap and add the trees or forests where they should be.

I noticed that far buildings blend quite nicely with the underlying orthophoto. At some angles and higher altitude, you can barely tell where's the limit. I'm editing the OSM2XP's textures for still better results.

Thanks MdMax ! :smile:

 

I have AlpilotX's addon, but this is for rural roads. We where talking about trees inside cities. Now I don't know if OSM allows to enter some lines of trees, but a generic solution would be very nice as well.

OpenStreetMap allows you to add individual trees (see the green points here):

http://www.openstreetmap.org/?lat=49.620472&lon=6.148545&zoom=18&layers=M

 

Then you can use OSM2XP, and link tags like "natural:tree" to a 3D object.

 

 

Another solution is this:

A small forest with a "landuse:forest" tag inside your town.
