P3Dv5 Excessive vRam usage

[mcdonoughdr 53]

Has anyone else noticed that V5 uses a crazy amount of vRam even on high end setups while running very minimal addons? I’m running an Nvidia RTX 2070 Super with 8gb and I’ve never ever come close to running out, yet I’ve crashed 3 times in the last few hours with various Nvidia errors about running out of memory.

Yeah, it's more important now. That's why it shows up by default when you hit shift+z to check your FPS.

Oh jeez, so is this a new chapter in the story of the OOM errors, except now it’s about VRAM rather than RAM?

Running a 2060 myself, oddly it shows only 5gb of ram total on the shift+Z info. Noticed Truesky clouds on high really eats it up.

8GB isn't a lot of VRAM anymore. Adjust the sliders to make it work for your system.

That's a ridiculous claim, I'm well aware of what my card is cartable of, and running a default jet in default scenery is zero excuse for running of of ram...

I thought a key point about DX12 was that you get additional performance but at the expense of memory management, so you have to be more careful as a user and developer (hence the VRAM in Shift-Z). If you want memory management but less performance there's always DX11 P3Dv4.

In addition to my view change CTD in v5 that I'm working on with LM on the LM forum, I also just 'ran out' of VRAM and had another CTD.  8GB VRAM, but in v4.5 occasionally in a complex aircraft at a complex add on airport I'd go over the 8GB dedicated VRAM and it would roll into the 'Shared' GPU memory. In this case, v5 seems to not want to use any shared VRAM and instead just crashes me to the desktop.  FWIW, settings way lower than in v4.5 and no ORBX installed yet...

From Virtuali at FSDT,  "Be CAREFUL with your settings, because P3D V5 consumes a lot of VRAM. A video card with 8GB is strongly suggested. Better if you have more...the sim now has an indication of your spare VRAM memory, so you'll know when you are going too high".  I take this to mean anyone with a midrange system or lower will have a lot of difficulty unless they drop their settings to the minimum, or close to it.  With my 4GB card, I know I don't have a chance until I upgrade.

Strange they did not change the GPU requirements compared to v4

[AnkH 2,261]

Haha, they brought us back the OOM issues. Nice...

They increased the recommended vram

I have a Nvidia GTX 1080 graphic card, that card has 8GB of VRAM right??

🙂 somehow they wanted to increase performance,  all the FPS chaser guys now happy with a default plane sitting on the appron showing 100 fps 🙂  vram can be tricky, very sensitive for CTD we will see, v4.4 no issue  so 🙂

Yes only the min but seems it's not sufficient (even before adding the complex add-ons)
