Right, you get steady 75 FPS because that is what your monitor is capable of displaying at the resolution you play AH at.  The AH frame rate display wont show more than what the monitor is capable of drawing with V-synch on, which is what you want even if it is much less than what it is with V-synch off. The eye cant really "see" more than 32-35 FPS so anything above that is gravy. If you have 75 FPS with V-synch on, leave it and you will have great frame rate, and no rubber bullits.

I limit my frame rate in the video settings to 45, no reason to go above that since I'll never see the difference between 45 and 75. This free's up processor time that would be spent drawing useless frames to be spent elsewhere.

If you are in a furball, and you "ping" a bad guy in one of those "lost" frames, you DONT get credit for the hit, its gone. The only thing in the AH system that "registers" hits is YOUR FE, so if your computer doesnt "see" it, it doesnt exist. AH waits for a screen "frame" to send the hit information, if your "hit" frame is lost in one of the ones that doesnt get drawn, but thrown away, you lose it and the information is not sent to the server.  If you have V-synch on, your computer will only draw another screen when the monitor is ready, and you will not have "lost" screens, and as a result, no lost hits.

First off I have to admit that I am not a game programmer and I am not an expert at the internals of Aces high. However intuitively I don't understand why it would work this way.  I could be totally wrong here, but let me explain what I am thinking.

First of all I believe the FE is more than just what you see on the screen.  I think of the front end as everything that is client side code (or in other words is running on your machine and not on the Aces High server someplace).

In order for anything to be seen on the screen it has to "happen" in the client side code first.  For example your "hit" has occur and some code has to decide that you hit a target and generate that graphic for you to see.  Just because that brief flash of shot gets dropped by your graphics card (because it can't display the frames fast enough), doesn't mean (to me) that the actual "hit" didn't occur on the front end and the appropriate response get sent to the server to let it know that it occured.

Of course I also don't understand why Aces High would wait for a screen frame to send information to the server, so I may be way off in left field.

I would love to understand this better though!

AH Does not have rubber bullet symdrome in the sence AW did.

Changes in vsync can make the gunnery look slightly different, and hence
people end up beeing 1 or 2 hit short of destroying a plane component. Even
thow they think they see the same number of hits.

We went so far as to implenent a hit checking persmision. And every time we
turn it on , (it shows you both client hits and what the host gets) they
have always matched for some one who thought that had rubber bullets.

On rare occasion there can be lag that will delay the destruction of a
compoent. But they will either be destroyed , or you will be dumped.
This type of occurance has nothing to do with vsync.

Well, thats odd, I was repeating what I thought Skuzzy had told folks about V-synch, but HT seems to be saying the opposite.

I have no idea now.

[straffo]

I've no idea either ...
so the lack of comment in my previous post

Where is the V sync setting located in AH2?   I could find it in AH1 but with the new interface it's been eluding me.

Vsync is not configured in AH but in your video driver (check display properties in the  control panel).

With vsync OFF I've some tearing in the image when changing view,that's why I've vsync ON.
