Not getting 30fps with Vsync and 30hz

[Quasimodo 505]

Wow, That XP11.50b3 is something else. The bottleneck is my 2080ti at 2150mhz at 99% while the CPU is ~50%. Unbelievable improvement is FPS. About 50% better.

So my problem is I set the monitor to 30hz in NCP and turn Vsync on in XP but I am still getting FPS well over 30fps. What gives?

Me too.

The strange thing is if I turn vsync off It locks at 30fps.

X-Plane's VSYNC only locks at 60FPS (as if anyone ever managed to do that). If you want the essential 30FPS lock, go to NVIDIA system preferences and set VSYNC to adaptive, half refresh rate.

I'll try that too. So long as its smooth and there is no tearing that's all that matters.😁

Unless you follow the instructions above, there will always be tearing.

Launch X-Plane from the command line with the "--lock_fr=nnn" flag or edit your shortcut accordingly ("nnn" is whatever value you want) and enjoy increased smoothness.

This is a bug, it happens to me too, locking @30fps with nvidia control panel does not work, even enablinig vsync within XP, frames go over 60. Was fine before b3, bug filed.

Will try Bjoern's workaround for now.

I found that it works using NCP adaptive, half refresh rate like Colonel X says, so long as the vsync box in unchecked in XP

--lock_fr=30

Although why on earth anyone would want to do that is beyond me. 60 at a minimum. 

I suppose if you prefer judging final like you just had 6 pints of strong ale 30 might be interesting.

If you have a recent pc ... I don't have the money to change, my processor is at least 5 years old.

I thought that's what I said at least that's what I meant to say.

Have you even tried it? smooth as silk for me on 4k monitor.

I haven't tried the Vulkan update yet, but the official 11.4x release does lock to my Vsync at 30Hz.  I'd be surprised if Vulkan can't lock to 30 (it did with AF2 with Vulcan) ... sounds like a bug.

Strangely with 11.4x sometimes the Vsync at 30Hz  would work sometimes not. When that happened the solution for me was to reload the nvidia driver.

flying at only 200kts - 100 meters per second, at 30fps you move 3.3 meters between every frame. That is not something anyone should be describing as smooth.

turn your head and you will literally see the gap between every frame - even in 2D, in 3D it will make you puke (physically sick as if you just had 6 pints of strong ale).

Rubbish.

I take it you would not want to use my Oculus rift S at 27fps via the use of the free ovr lua plugin then?

For anyone interested x-plane 11.5-3 beta works great in vr with the visual effects set to medium, texture quality high, world objects at maximum. with the proviso you free your mind over 27fps.

h' no.

I like blasting through mountains at mach 1+, plus the rift is nowhere near as comfy as the PSVR.

like this

I'm beyond ATPL in simulated VR hours now (1,558 hours in SteamVR according to my steam library)

Yes you did say that and I should have acknowledged. 😁
