Fenix A320 and SU2 performance


ISSUE DESCRIPTION

Description of the issue: Whenever using the Fenix for more than 15-20min, VRAM usage will suddenly spike and there is no way to get it down again. Even with lowest settings and 50 TLOD.

[PC Only] Did you remove all your community mods/add-ons? If yes, are you still experiencing the issue?
YES

FREQUENCY OF ISSUE

How often does this occur for you (Example: Just once, every time on sim load, intermittently)?
Every time I do a navigation flight in SU2. Other aircraft like A330, A350, B787 don’t even use half of the VRAM (especially in cruise). On startup, everything seems okay, no excessive VRAM. But after a few minutes the VRAM is maxing out…

REPRODUCTION STEPS

Please list clear steps you took in order to help our test team reproduce the same issue:

Just did a change from FNX A320 to INI A330 and can confirm, Fenix is using way more VRAM.

Fenix is honestly not really playable. Regret that i bought it so far. Just wasted money.

Hi there, I havn’t been able to recreate what you are saying occurs. Spawned in at drzewiecki RJAA. Latest SU2. We have different cards and system settings but I would expect to see similar behaviour on my end.
I think you’re just really up against it when trying to get good performance out of 8GB of VRAM and a complex airliner like the fenix. I’m not commenting on whether it should be that way or not, just that in my experience this doesn’t seem to be a bug related to SU2 and the fenix specifically.


Spawn: VRAM 11.47GB


20 minutes later during pusback : VRAM 12.19GB


15 minutes after takeoff: VRAM 10.9GB
