What version of Windows do you have? Have you updated Windows in the last few days? It's hard to find a solution without knowing if you installed something new in the sim or the PC before this problem occurred. I solved all my problems with instability and fps drops, OOM, CTD, and Resource Exhaustion simply by uninstalling X-Box Game Bar and all its similar ones from the PC. However, if you give more information we'll see what it could be. If P3D goes into CTD attach the Event Viewer log (.xml)

Probably found the component which cause issue with the last Windows Update. Open task manager while P3D is running and "reset scenario" from menu P3D a couple of time until you can see on your Task Manager the process XBox Game Bar (there are 2 process one with the X-Box logo and one without). Leave it run and see CPU and RAM usage increase. Terminate process and resource should reduce. If you see this happening here the solution: Go to Settings > System Components. Find Game Bar and click on it. Click the Advanced options link. Under "Background component permissions," select Never. Let me know if this can help or fix P3D also on your PC

I had similar problems with the latest Windows 11 update, but it affected my resource usage (VRAM). I use P3D v4.5 and haven't a CTD in about four years. However, after the latest Windows update, P3D stopped running normally. When I launch the simulator, it initially works as usual, but after 10 to 30 minutes, the VRAM usage increases from the normal 1.9GB to 9GB without any clear reason. This causes the PC to stop the program due to resource exhaustion. I believe the main issue is related to the .NET Framework or the C++ redistributable, but I can't be sure. Anyway, I managed to resolve the issue by uninstalling the latest updates (you can do this in the Update History section of Windows Update). Another possible solution is rolling back to the Windows 11 24H2 Repair Version, which can be found under Advanced Options > Recovery. It’s a large file, so the rollback process takes some time, but it fixes all the problems.

Hello, I have encountered a strange issue related to the latest Windows 11 update. My P3D V4.5 has been extremely stable (the last CTD occurred about four years ago). However, in the past few days, I received some updates via Windows Update that have negatively impacted P3D, causing low virtual memory conditions and frequent CTDs. It is an unusual problem affecting my PC's memory. When I start P3D, everything appears normal as usual. However, after 10 to 30 minutes, RAM usage suddenly increases to its maximum without any clear reason, despite not having installed any new add-ons. In Task Manager, I can see the RAM usage rising rapidly from 1.7GB to 8–9GB, eventually leading to a P3D crash. Has anyone else experienced this issue after the latest Windows 11 updates? It seems very odd, and I suspect it might be related to the release of the .NET Framework or the Windows Malicious Software Removal Tool x64. After uninstalling these updates via Windows Update, P3D is running flawlessly again. Additionally, I noticed that when launching P3D, RAM usage has shifted from a low 600MB to around 2.0GB. Do you have any solutions? At the moment, the only workaround I have found is to revert the update. Any advice would be greatly appreciated! Thank you in advance.

Hi, send me a PM with your email. I've got 2 different version: the original produced by Milviz for P3D V4. and one revisited by me (RIP files) very fps friendly if you have a not powerful PC. The PC-6 with Real Light + True Glass and Milviz's PBR could be a fps killer if you flight in HQ scenery or with bad weather. The modified version have only the bush wheel tires and amphibian version of the plane (not skis version and inline float). This version haven't also the original livery but some different made by me and converted from MSFS. Tell me what do you prefer

Hi all, would to like to share with you my rendition to this great aircraft! DeHavilland DH.88 Comet Rendition Manual.pdf - Google Drive Send me a PM with your email if you're interested in a copy.

Hello, there isn't animation in the mdl files for the pontoons. So is not possible to retract.

Wow! Running P3DV4.5 very smooth at full high setting also without a dedicated GPU! Absolutely strabilliant! Anyone found a method to remove the double tooltips?

Hello, I try to connect with engine weather P3DWX but I have errors and no real weather. Do you have the same problem? Thanks, Dan

Hi there, is possible to have this mod? I try to contact @Novej757 but I can't send message to him I don't know why. Any help is greatefully accepted! Many thanks in advance!

No, there are a couple of GA aircraft such as Diamond DA62, Diamond DA40 and ultralight Jabiru J160/J170. All works with minor issues on P3D V4.5

Hi everyone, IRIS FSX and P3D products are now freeware: https://store.irissimulations.com.au/iris-simulations-classics/ Click on the red link below in the page to access the dropbox repository.

Same for me. Website is down, hope a temporary issue.

Hi thanks for your replies, developer answered to my mail and he told me that some work on hosting was gone. Anyway now the addons works correctly, but I think it could happen again. So I asked him to remove the internet check for his existing customers. No reply from him yet. It's really bad that people can't use the paid addon because something in the server goes wrong. Today most of the P3D addons are free I don't understand why keep this check when these addons won't have more updates. It's just frustrating that you can't use something you paid for because you don't have an internet connection or maybe the server has or will have problems. The check is probably in a dll file (looking with IDA), and affect models itself. I hope he changes his mind and gives his customers a patch to remove the internet-check.
