In reply to Lamont A.

If you get 30 fps with the LR planes on GL and max tex res, we are aiming to get 30 fps with Vulkan/Metal and max tex res for those same LR aircaft.

If you get 15 fps with the TBM on GL and max tex res, we aim to get one of:
– 15 fps with Vulkan and the TBM on max res OR
– higher than 15 fps with Vulkan and the TBM but the textures NOT looking as sharp.

Here’s why:
– The OpenGL driver is _not allowed_ (by the GL spec) to lower tex res when the app is overloading VRAM. It has to juggle things into and out of VRAM to draw at full quality, performance be damned.
– We have designed the Vulkan/Metal back-end to NEVER juggle things into/out of VRAM mid-frame because if we do that we cannot guarantee that you won’t get a stuttering disaster.

If the TBM overloads VRAM and the GL driver is swapping, you might get either (1) consistent but low FPS or (2) stuttering. If your 15 fps is consistent but low fps, that is _not_ a case we will emulate in GL.

I should probably leave this for when you are ready to get your hands dirty with Out of VRAM errors… but since the question is more of a goal question than the ‘bug’ itself…

So you said “You do not need more VRAM to run with Vulkan than OpenGL” .. but I also read one of you mention something about “settings to far right”.. I am just checking. Since opengl let me put my settings all or mostly far right if i really wanted to. With 11.41 and textures and objects full right, even with 2gb of vram my system can get 30+ fps in a laminar plane or even a light 3rd party plane and no errors. In a plane like the tbm 900 i get 15fps (which is generally too slow to fly but for testing sake i did it) and NO complaints from x-plane.

With a laminar plane and the same airport in 11.50 with textures and objects all the way right i get the error. It starts out looking good but then the quality melts away. and then poof.. vram error and xplane exits. Obviously you already stated you will work on it so Im not saying anything new…

Im asking if the goal is that a GPU that could run in opengl with the major settings full right without errors, will be able to run w/vulcan with the settings full right without errors.

Keep up great work. beta looks awesome so far!

Any chance for this beta 2 to be compatible with us Valve Index VR users? Last time I’ve tried it, only the X-Plane 11 VR mirror was showing my headset responsive, however, it only shows the loading screen with the mountainous background in the VR headset. But I’m seeing posts about people successfully playing this in VR. It works perfect in 11.40, however, so I can fully confirm my hardware is working.

I’ve tried Beta 1 and Beta 2, I cant run X plane. Im using the steam version, when I try to launch x plane, nothing happens.

In reply to Sidney Just. IVAO Pilot Client does not show surrounding traffic, can see it only on TCAS:(

Good morning X-plane team, I have been noticing in the 2 beta versions (beta 1 and 2) that the Toliss aircraft the A321 does not have any sound, but the optimization and improvement of FPS is incredible indeed, very good work If the remaining errors such as crashes are gradually improved, sound failure in Toliss aircraft. In addition I have seen another error, the runways come out completely flat as if it were this P3d or FSX: or, kind regards and take care.

please update the cirrus sf50 and the xplane1000 nav data and change weight and balance so you can put weight in each seat and the baggage weight in the back. some of the real world aircraft have something called baggage extend seeing what that would do to cg would be nice. seeing something like xplane 1000 nxi would be sweet or maybe even a xplene 3000.

Will there be an option to cap the framerate at 60 or 30 fps?

VR works great in Beta2. The wind mills don’t have a moving rotor… is this a bug?
