P3D V5 HF1 In-sim V-sync has changed - can't undock panels!

[Caveney737 66]

Hi All

Just upgraded to v5 and wow, it is so smoooooth. IMHO, one of the reasons for this

might be because v-sync in the previous versions never worked properly but it is in v5!

The problem is, now it is fixed you can't undock panels without the dreaded halving of 

frame rates. In previous versions, this only happened when you used an external frame

rate limiter such as nvidia inspector, but now it happens if you just use v-sync in the sim.

Before I report this to LM, I would be grateful if someone could confirm it for me by trying

to un-dock say a GPS panel in one of the default aircraft. If you are using the in-sim v-sync

to run at say 30fps, you should see your fps halve to 15. If you turn v-sync off, the frame rate

returns to normal.

I would imagine this will affect a lot of people who use v-sync and like to un-dock panels

to move them to another screen e.g the GPS.

If anyone else has already discovered this or knows a way around it, I would be very 

grateful for any help.

Cheers 🙂

 

UPDATE:  I have now found that if you turn Triple buffering ON the problem goes away

but if it is OFF the frame rate halves again - very strange, but at least a solution if any one

is interested !
