Ok, Thanks, that makes sense..

If you mean numerically, it varies based on monitor(s) resolution, settings, AA, aircraft, scenery, add-ons…basically once we don’t have anything else to _put_ in VRAM, we can’t just fill it up with made up data. But the actual upper requirement (where you’re avoiding some paging, down-res, AGP traffic, etc.) depends on content.

Thanks for the answer Ben. can I ask what this limit is?

We do have an upper bound on VRAM use – in that if you have no more content to put in VRAM, we won’t just fill it with junk. So there isn’t infinite benefit the way there might be from (theoretical) infinite clock speed.

No, I’m just asking that if I had 24G of VRAM instead of 11G, if X-plane would use it all if needed, or if there is a limit set on the software for that.

Our experience is that 20.8.3 crashes intermittently, but has never not had that problem -the crash stats match that.

so? it’ there to be used. would you feel different if xplane always kept e.g. 2gb free?

Solution, use the privative drivers (amdgpu-pro). The result is slower in fps, but all is running OK.

Thanks

Rather odd experiences recently. 20.8.3 has been working fine, but today launched with an error. Subsequent attempts all fail now and XP just crashes. It’s as if something has changed over the last couple of days – saying that, nothing different on this end – just a bit weird …

Somewhere in there, some programs used cassette tapes, but, as I recall, SubLogic was always on floppies.
