This is an issue with 5.4. There is a lua script available somewhere to fix this, you can also revert back to 5.3.

Worth it is a relative term, but I don't think it will give more FPS. It may let you use more eye candy in the sim while maintaining acceptable frame rates, but that's about it.

I run a 4080, and the only time I even run close to running out of VRAM is with the TFDi MD-11. I also push the GPU pretty hard, and I only have a 9700K. I use: 4K textures 7cm textures 4X SSAA Ultra Shadows TEXTURE_SIZE_EXP=10 2560X1440 Resolution. I don't think you problem is VRAM related.

Your best bet is to reach out Rex to make sure the registration key will carry over to P3D V5.

5.3HF2. I run QW787 V1.4.

Interesting, I have never had those issues with the 787, I personally think it is great for it's price point and target audience. It is a bit slippery while descending, but so is the real thing as I have been told.

I can confirm that disabling Real Light saves about 1.0 - 1.2GB of VRAM on my RTX4080. The beacon and nav lights are still way overblown with RL disabled. Hopefully these issues get sorted soon.

Did you change to a different frequency on the com radios in the aircraft?

Well, I maxed out 16GB of VRAM with a 4080, so that is beyond disappointing for textures that are definitely not 4K. Also the external and beacon lights are way overblown and completely unusable at night. This is 717 release debacle all over again.

Are you overclocking your CPU or GPU, or both?

Hopefully you still have your 5.3 install package. LM only lets you download the latest release from the website for each version that you purchased.

I believe you experiencing a known issue with the area around Clacton (EGSQ), which for me has caused the exact same symptoms you are having in P3D V3, V4, and V5. I used to know what caused it but I don't remember what it is. But the moral of the story is this is a P3D issue, nothing to do with your system.

How does that work? Thanks,

P3D is not a true fullscreen program, it is actually borderless window which may not work with Smooth Frame.

If you select Ultra shadow distance settings in V5, it also will eliminate this issue.
