First of all, I am aware both AS P3D and EA/trueSKY are in beta, so what follows is not a complaint. (Even in it's current state, it's already a game changer imo.)

I noticed that when I have both of them running, it sometimes happens that EA is suddenly turned off, which I believe is caused by AS. I could replicate the situation:

FlyTampa EKCH, runway 04R, PMDG 737 NGXu:

EA is deactivated quickly after loading the scenario with AS turned on.

EA is not deactivated at all after loading the scenario with AS turned off.

So, everything else being equal, AS looks to be the culprit. My question, is this a random glitch or a conscious effort to save VRAM and prevent P3D from crashing due to a VOOM?

I noticed VRAM usage is quite high at FT EKCH, hovering around 6 GB, going up to 6.3 GB at the very maximum. 6.7 GB I have available according to P3D (my RTX 2060 Super has 8GB VRAM). Is that margin sufficient? I didn't experience any crash but thought it would be good to know if there is a "recommended" amount of VRAM you should have left.

Thanks a lot!

I have the same here. From what I have heard is a safety function in P3D to prevent VRAM CTDs.

Interesting, I've read the exact opposite on the LM forum, that it must be coming from an external application (i.e., ActiveSky).

I have just done another test, sat in the VC @6GB VRAM usage for a while, started up AS, and boom: EA gone. However I couldn't find any setting in AS that would cause this. So I'm thinking it's a compatbility/weather injection issue.

I use to start AS before starting P3D, with seeing myself the problems above I find loading a flight, wait to your at the gate, everything is good then start AS.

That seems to work for me.

I use AS and EA for every flight, and this has never happened to me in 3 months/hundreds of episodes. So it's not something that is inevitable by any means.

The only thing that has ever made EA fail for me is trying to run VR in single-pass mode, which is not supported. The sim puts up a warning box, and tells you that it is deactivating EA.

Re: the safety feature that you allude to. That's Dynamic Texture Streaming. Do you have it turned on? If so, why not uncheck it as a test (it's in the Display menu), and see if you still drop out of EA.

 

I had this happening also pre HF2 and 2004, was really annoying and I think it is related to VRAM. TBH P3d 5.0 is really annoying lol, cant wait until 5.1 as for me this release has put me off simming altogether as they've given us a taster of whats to come yet we cant use it properly.

Wonder how much longer we have to wait until trusky is out of beta?

My clouds with EA on will disappear and come back later. Using AS. I'll have to try the load after being in the sim method.

I seem to recall EA can sometimes reset if you have a CTD.  Probably worth checking your graphics settings from time to time.

After some further experimentation I could narrow it down to situations where VRAM usage hits or exceeds 6 GB. If usage is < 6 GB EA with AS stays on without any issues. Dynamic texture streaming is deactivated. I'll probably head over to Hifisim and see if they have a solution, because even if this issue not caused by AS, it is related to it in any case.

I guess it's time for me to get a new 24gb Vram card!

I've never been close to the 7.1GB limit (thanks to the Windows update 2004), although different setups (4K, etc.) may demand more VRAM.

So I had an epiphany to delete my P3D.cfg and, lo and behold, AE doesn't deactivate itself anymore. That is, despite using the same settings as before. VRAM still goes > 6 GB obviously although I am sensing a slight decrease overall. Sometimes it is that simple...
