Autogen V4

[pmb 5,137]

At first, autogen popping is much less noticeable than in Prepar3d3 on my system. Its visibility depends on a number of factors like weather, possible shader tweaks etc. There are regions where I don't notice it at all but there are others (like the plains in Silicon Valley) where I still find it distracting.

There is a parameter

AUTOGEN_DRAW_DISTANCE

under SCENERY which regulates this. It defaults to 30000.000000.  Raising it to, say, 45000.000000 mitigates the remaining autogen popping, however at the price of (i) remarkably longer Prepar3d startup times, (ii) a noticeable fps loss.

Kind regards, Michael

@pmb thanks, i havn't tried that, however the more alarming fact is i dont have any autogen whatsoever after about 5min. Its like P3D just gives up loading it. I dont even have blurries, the textures are pin sharp.

Do we have a feel for how much autogen loads the CPU in V4?  I was under the impression that autogen rendering had been pushed primarily to the GPU, but I will defer to others more knowledgeable on the topic.

Autogen has been rendered by the gpu using tessellation since P3Dv2 launched.

Try the AG Distance slider. If set to the left you will see almost nothing. From Medium (12000)in the P3D.cfg file ) and upwards you will see lots of AG.

Surely you will have to set both AG vegetation and buildings sliders also to more than all the way to the left...

I have exactly the same problem.
I have reinstalled the sim, drastictly reduced the settings but still have have these problems flying the fast jets.
Running with a 4790K at 4.6 and a 1080ti.

All suggestions i've read till now don't seem to fix the problem

Add TEXTURE_SIZE_EXP=10 in your Config.  This will stop the autogen popping, this will use almost all of your VRAM though.

With regard to the usage of cores,  what would be the best tool to monitor that usage while P3Dv4 is actively running?

@everyone  Thank you for your ideas, im still working through the problem. However, ive made progress by reinstalling the client. Still have further testing to do.

Task Manager will display core usage but only for the last minute. Try MSI Afterburner - you can set it up to monitor all of the individual CPU cores in the Monitoring tab of the properties. It will show about 10 minutes of usage.

I've also been having this autogen issue with v4 - I've created a thread on the LM forums but haven't had any feedback yet:

http://www.prepar3d.com/forum/viewtopic.php?f=6312&t=125808

I've just done a "quick and dirty" test:

With settings pretty much maxed out I took off from Manchester EGCC in the Carenado Citation and flew to Gatwick EGKK but stayed at 3000ft @ 280knts the entire flight and I had thick, luscious autogen out to the horizon for the entire flight.

Restarted the sim, same settings and the same flight - but this time I climbed hard out of EGCC to FL300 then bascially glided back down on approach to EGKK. In this second sceneario I had the autogen problem, once I descened through the cloud base at around 5000ft and the ground came into sharp view I had absolutely no autogen to the horizon in any direction. I flew on at 4000ft for about 4 minutes and some autogen started to sporadically render, it wasn't until I paused the sim for about 1 minute that my autogen came back to normal!

All other elements of the scenery were perfect - beatiful sharp textures.

No lag or stuttering and my fps were solid the entire flight.

Odd!

Replacing client puts the shaders back to the original, just something to think about--When I use PTA I eventually end up with problems with sunlight, I can change view direction and sun on ground and other objects disappear , change view and it's sunny again. This got to be irritating so I reinstalled client to get original shaders again. Then view directional changes don't play with sun effects, I forget, start using PTA and end up with the same "sun" problem. The last week or so I have stayed a way from PTA and I still have sunlight without the view changes losing it. 

If you fly for a while without PTA you get used to it. I find it a lot better than making a 180 turn and either losing sun when it should be there or gaining it when I shouldn't. I can only attribute this problem with playing with the default shaders.

I consider Process Explorer a great tool to watch your pc activity whilst in sim. Gives far more info than task manager. on cpu and gpu and is low drag on the machine.

You do realize that you don't need to reinstall the client to get back the original shaders? PTA has an option to revert back to them.

Interesting... i may do some tests as i've found this to start happening with my setup, and i couldn't remember if it was doing this or not before PTA.. i also have very annoying cloud shadows popping in and out of the periphery of my view when panning, using ezDok along with the sudden changes in colour/tone. Everything in sunshine one second and then everything in shadow/grey another..
