Rainero 7 Posted May 16, 2020 Share Posted May 16, 2020 Hi, thank you very much for the P3Dv5 update of Lukla. However, for me it is unusable. Sitting on the ramp with my A2A 182 I have 15fps, when running down the runway the frame rate drops down to 2 fps and makes the airplanes uncontrollable and leads to a crash of the plane. In P3Dv4.5 I have 35fps on the ramp and minimum 26fps when running down the runway. Can anybody confirm? Link to comment Share on other sites More sharing options...
Rainero 7 Posted May 16, 2020 Author Share Posted May 16, 2020 Now I tried the AS DHC-6 300 Yeti Airlines, I think it comes with Lukla, and it is even worse. When switching to the spot mode and panning around I see a DXGI_ERROR_DEVICE_HUNG error. I have never seen this before. I have a nVidia GTX 1070 with 8GB RAM. ORBX Global installed.

BTenhaaf 6 Posted May 16, 2020 Share Posted May 16, 2020 Do you have Hotfix1 for Prepar3D v5 installed - as this is an error message of the first edition of P3Dv5 ? I haven't got this with HF1 until now. Link to comment Share on other sites More sharing options...
Developer OPabst 2091 Posted May 16, 2020 Developer Share Posted May 16, 2020 This is an known issue in V5, please reduce the Graphic settings, special the max Texture size to keep more VRAM free. A hotfix 2 is in development. Link to comment Share on other sites More sharing options...
Rainero 7 Posted May 16, 2020 Author Share Posted May 16, 2020 I have version 5.0.24.34874 installed (complete package, not only client), which should be HF1. Link to comment Share on other sites More sharing options...
Rainero 7 Posted May 16, 2020 Author Share Posted May 16, 2020 @OPabst: Thank you. I will start trying with reduced settings. I just wanted to know if I'm the only one (problem with my setup), or others have the same problem (RAM demanding scenery) as well. However, P3D should not crash. So there is a problem with P3Dv5 in either case. Link to comment Share on other sites More sharing options...
Developer OPabst 2091 Posted May 16, 2020 Developer Share Posted May 16, 2020 You are not alone with Vram issues, it‘s a general issue in P3D V5, but full addressed to LM Link to comment Share on other sites More sharing options...
Rainero 7 Posted May 16, 2020 Author Share Posted May 16, 2020 I reduced texture size to 2048x2048 and now I have 4.1/6.6GB. That looks okay. However, as soon as I'm on the sloped part of the runway my frame rates drop dramatically down to 1.8fps. In the moment I got airborne the frame rate jumps to 20fps. That looks to me as if there is a problem the the sloped runway and P3Dv5. Anybody else having this effect? Link to comment Share on other sites More sharing options...
JarredP 50 Posted May 16, 2020 Share Posted May 16, 2020 That means your video card is streaming data from regular RAM and that process is very very slow. You still need to bring settings down some more most surely. Link to comment Share on other sites More sharing options...
Rainero 7 Posted May 16, 2020 Author Share Posted May 16, 2020 Mmmh... but why only on the sloped part of the runway? I will try. Link to comment Share on other sites More sharing options...
hobbyflyer 0 Posted May 16, 2020 Share Posted May 16, 2020 Hello Rainero and all the others No, you are not the only one. I have a really quick system with 1080 ti and 11GB ram and I have got a framerate like a Dia-show. It is impossible to roll and to fly in a suitable way. This is the worst piece of software I installed the last two weeks since HF1 is out. I think we have to wait until anybody will solve this heavy problem- Link to comment Share on other sites More sharing options...

I think we have to wait until anybody will solve this heavy problem- It is maybe possible, that there is a platform use to build the runway area. In some cases this platforms generate the issue you see. When the aircraft is above (not needed to be on ground) of this area, the frames drops down to very low frames. Seams to be an issue, when the sim calculate the ground distance between aircraft and the platform below. With El Hierro this issue was reported in V5 too, even when I don‘t see the issue in testing the scenery before the release, I could recreate it later. After recreate the platform file the issue was fixed. I will point the developer of Lukla to this issue here, so maybe he can fix it the same way there.

ulimcologne 0 Posted May 18, 2020 Share Posted May 18, 2020 Rainero, I have exactly the same problem like you. And my settings are really not very high. My graphic card is a RTX 2070 and where ever I fly my fps is stable between 20 and 30. ( Köln/Bonn with Orbx GES/GEN, Orbx LOWI, Mallorca Prof, etc with the AS A330 running and active sky). In Lukla with the DHC 6 everthing is fine as long as I'm far away from the runway. As closer I come to touchdown the fps decrease. After touchdown the fps decrease to 2 and lower and the plane is not longer under control. Getting to the touchdown is only possible without active sky activated. If I activate acvtive sky I have the VRAM issue before. Something must be totally different here with this scenery campared to the other sceneries I have installed. By the way, the smaller airfiels inculded in this scenery like Rumijatar worked without problems. So I can totally confirm your experience with this scenery.

Rainero 7 Posted May 18, 2020 Author Share Posted May 18, 2020 Thank you for the feedback Uli. I'm pretty sure, the devs will find a solution for this issue. Link to comment Share on other sites More sharing options...
Developer OPabst 2091 Posted May 18, 2020 Developer Share Posted May 18, 2020 The platform to build the ground of the hill and runway is the source of the bad frame issue and a workaround in testing by the developers. Link to comment Share on other sites More sharing options...
pbearsailor 9 Posted May 18, 2020 Share Posted May 18, 2020 Just a note that I have the same issue. Frame rates and VRAM are fine here and in everything else I've flown except for the sloped runway at Lukla. Cannot use at this point. cheers steve Link to comment Share on other sites More sharing options...

Sasa 921 Posted May 19, 2020 Share Posted May 19, 2020 We're on it and will supply a hot-fix very soon. Bests, Sascha Link to comment Share on other sites More sharing options...
Pinepix99 1 Posted May 22, 2020 Share Posted May 22, 2020 Having the the same problem with the V5 install. Glad you are looking at it. I had V5 pointing at the V4 implementation of Lukla and it worked fine Link to comment Share on other sites More sharing options...
Goofey007 24 Posted May 25, 2020 Share Posted May 25, 2020 Same here, slideshow when running down the runway. Once airborn frame rates are up. Looking forward to hotfix Johan Link to comment Share on other sites More sharing options...
