DLH560

Hi Frank, Thanks for your kind reply. Yesterday I tested a long haul without SMP and RWC at all. After about 7 hours of flight the whole PC crashed with a blue screen - never had that before. I tested a lot and also figured out that the terrain radar data of the Flight Factor 767 was corrupted. Obviously there are several problems I need to solve. Concerning the memory usage of the graphics card: Camping at Mr.X6's KBOS scenery and running my setup, the VRAM (checked via SkymaxxPro) was already eating 6.9GB - just 1.1GB left. And checking those 6.9GB, HD-Mesh and UHD-Mesh have already been removed from the system. Removing SMP and RWC, the VRAM usage was still at 6.5GB. I just wonder that all my crashes occur over the atlantic ocean when no scenery needs to be drawn. My next test flight will be with reduced shadow effects ("3D on aircraft" instead of "melt your GPU"). Camping at the gate, my FPS went up from about 43 to 48 at the worst angle of view. I did not consider any performance issues so far but maybe the whole system gets unstable. However reducing the shadows has no impact to VRAM. Changing HDR AA from 4x FSAA + FXAA to 2x FSAA + FXAA has no impact at all to FPS - no idea if it would increase stability. Killing the HD sceneries would be a terrible step that I try to avoid - it is just too nice to be awarded for a long haul with a beatiful scenic view upon arrival. But what I do not know is if i.e. a bunch of HD airports in Europe will have an impact to the system when flying inside i.e. US airspace. If this would be the case I could easily swap the respective files. But on the other hand the default scenery list is growing too - update by update. This then would have some impact too - is that true? I really love the SMP and RWC clouds and look forward to using them again. But at the default 2500 square miles I hardly see any clouds at FL380. Before my series of crashes started, I testet SMP and RWY with the cloud range totally maxed out and had some stutters. Reducing them step by step to 14000 square miles all stutters have gone and the system was rock stable. Then the first crash started out of a sudden and I reduced the SMP cloud range to 4096 square miles at stable 55 to 60FPS when airborne - it crashed again. Also I thought that if the PC is running out of VRAM, it would grab some RAM (at lower FPS rate). 64GB should be quite some help here. Obviously I was wrong here - the graphics card seems to be dependent on its own VRAM. I never had these problems before and this is what really drives me crazy. I'll keep on testing. Thanks for your feed back! Regards Marc

Hi Tony, This is what I did when I replied to Cameron's initial reaction on my graphics card - no reply yet. After X-Plane crashed again (see my post above) I now do a flight without SMP and RWC. I must admit that the clouds look less beautiful (but not ugly). On the other hand my FPS rate went up significantly! I always thought SMP would increase the FPS rate over default. Now I have the proof that this is totally wrong. The default clouds (set to 60) show about 8 to 40 (!) frames more than SMP 3.2. SMP 3.2 was set to crisp textures and 4096 square miles. The extra performance boost by default clouds is a nice compensation over the beauty of SMP. If this flight will run stable I will continue testing without SMP (and maybe quit SMP until some more stable version shows up). Regards, Marc

Hi, I logged in to X-Aviation using the dedicated support form and filed all data. Cameron then asked me about my graphics card via e-mail and I replied to his mail - without any further answer. I sent more log files over the time and reported all findings I collected over the time - still no reply. I refiled my latest findings via the dedicated support form again - no reply. Therefore I registered to this forum and filed my logs again - including a log that was less than 60min old when I posted my report. Yes, my latest log shows SMP 3.1.2 instead of 3.2. As I said before, I am stilling having the problems. Without any reply I obviously need to try to help myself. This why I continue testing. I thought it might be of help to provide as much information as possible. Currently I am testing SMP 3.2 without RWC. At present it seems to work, but I just departed 30min ago. As I prefere long hauls I need to wait until I a have landed in about 11 hours to know more. I am sorry that you don't believe me that I filed all data the way X-Aviation indicates to be correctly, but that's what I did. And since Cameron gave an initial reaction on my graphics card (I also stated that in my original post), I felt quite certain that I did the right thing. If X-Plane crashes again the next time I reactivate RWC, I will file another log. But the final actions before crash are always METAR parsing - even the one with SMP 3.1.2. Since SMP 3.2 was discussed to have the problem I thought it might be of value to know that also version 3.1.2 has the problem - obviously you are not interested in it. Regards, Marc Edit: Crash again! But now it was different: SMP 3.2 used RWC deactivated (folder moved away from -Plane installation) final activity before crash by SMP but no clear statement that SMP actually caused it crash to desktop over the atlantic ocean - more about 1000nm away from any default or custom scenery Log.txt

Hi, I am sorry having to say that the story of crashes has not come to an end for me yet. After about 20 crashes using Skymaxx Pro 3.2 and the latest version of RWC I tried stepping back to Skymaxx Pro 3.1.2. Hoping that this will do the trick I was just camping at a gate of KBOS when X-Plane 10.45 crashed again - even with version 3.1.2. The log clearly stated that it was Skymaxx Pro that crashed the SIM to desktop. I also use the combo of NOAA plug-in, SMP, RWC and XSquawkbox (latest version). I will now try SMP 3.2 with NOAA and without RWC - no idea if this will bring back stability. I am really running out of ideas. I have filed several reports to Sundog via the support feature and via e-mail and sadly did not get any feed back yet - beside the question if all trouble started after installing my Nvidia Geforce GTX 1080. To also answer that question again: The GTX 1080 is still brand new but I did more than a dozen of long hauls using it without any issues. All my trouble came with RWC and SMP 3.2. Now since RWC and SMP 3.1.2 also turned out to crash my X-Plane, I have no clue what to do. I have attached two logs for SMP 3.2 crashes and one log with the latest SMP 3.1.2 crash. Any help is highly appreciated. Regards, Marc 00 - SMP 3.2 - Log.txt 01 - SMP 3.2 - Log.txt 02 - SMP 3.1.2 - Log.txt
