[Bug-gnubg] Vsync?

[Rich Heimlich]

Guys, we've gotten to the bottom of something with GNUBG and Nvidia cards.

I couldn't, for the life of me, figure out why my supposedly blazing 
fast new 8800 card could only get 60fps in the Test Performance in the 
game. I then got on the Rage3D forums and finally got some Nvidia guys 
looking at this (I've been ATI forever) and they nailed the issue. By 
default gamers have Vsync set to Application Preference. Due to an issue 
in Flight Simulator it's recommended to set it to FORCE OFF. When I do 
that with GNUBG my performance shoots through the roof to 200fps (and 
more) and it plays smooth as glass. With that set to app preference even 
at 60fps the dice rolls and movement are choppy about 40% of the time.

After testing a bit it seems the program is forcing Vsync ON.

Is this accurate and, if so, is there a reason for it? Can we get an 
option that allows the app to turn it off so that I don't have to force 
it off?

It might also be helpful of Test Performance were enhanced a bit to 
bring up its own screen to explain some things that are addressed and 
other things that can be done to help improve performance. If I were 
pointed to Vsync I could have save a lot of poking around for a long time.
