Limit FPS on AMD cards? Without V-Sync?

Trying to figure out a way to limit the FPS in all games like you can nvidia. Just built a new amd gaming rig. So far i'm liking nvidia more just due to it's simplicity.

So is there a way to limit the FPS without turning on V-Sync? If so could you explain how this can be done? Thanks!

Erm...
There is a 3d settings for gaming.
There are a settings named Frame rate control in here Catalyst Control Center 13.4.
I not sure how it work.

uh...... i don't know if there is one for radeon....

but....

It's Dynamic V-sync that you can choose your own frame limts to set it to.

cause if it's not 60 fps it's 30 fps lol.


That's incorrect. Vertical Syncronization does exactly what it sounds like: It syncronizes frame rate to the vertical refresh rate of your monitor. http://en.wikipedia.org/wiki/Screen_tearing#V-sync


great job on taking it from the screen tearing page of wiki which does nothing to explain what actually happens or how vsync is achieved....

read this..... and you're as wrong as wrong can be lol.

Then there's adaptive vsync and dynamic vsync.

but you avoid severe screen tearing, which imo is worse on the eyes than running 30fps. Just trim your in game details back to lift the fps so your hitting 60fps most of the time. Everyone is always on about wanting to max out game settings, but without the highest end equipment you aren't going to be able to do that and hit 60fps most of the time. You can also try dropping to 50hz on your refresh rate then you only have to hit 50fps and its still pretty smooth.

From your link "What is VSync? VSync stands for Vertical Synchronization. The basic idea is that synchronizes your FPS with your monitor's refresh rate.". All of the other factors he cites only occur when your FPS drops below your monitor's refresh rate, something he explains in detail.
In what regard was I incorrect?

you said that if it isn't 60 fps then its 30 fps as a result of vsync is incorrect.

unless you have adaptive or dynamic vsync, your computer will lock you to 60/30/15/etc (or whatever your screen's refresh rate is and etc)... fps once the frame rate falls lower than each threshold...

Is that what you were trying to say? My apologies. From the way you'd phrased that, I took it as the (rather odd) assertion that standard VSync locks framerate to 30 FPS.

Edit: For reference, I parsed that incorrectly due to missing the "if", and thus reading it as "cause it's not 60 fps it's 30", thus causing my response.

So in short what I'm seeing is AMD just sucks for compatibly or having custom settings. So far it seems nvidia is light years ahead when it comes to user experience. Which sucks because IMO AMD has the better GPU. Yet nvidia just seems a ton better to use overall.

Most games today will not do that. Most games today use a form of triple-buffering that is built into the game engine. This prevents v-sync from dropping FPS all the way down to the nearest divisible refresh rate. However, you'll see see alternating between 16ms and 33ms frame times, which may seem jittery to some.

That said, RadeonPro has a couple options to limit frames. Either with Dynamic Vsync that works similar to adaptive v-sync, and dynamic frame control or something similar in name, which is strictly a FPS cap.

MSI Afterburner and EVGA PrecisionX also allow you to set max FPS, but this method does not let you set them differently for each game.

triple buffering is a terrible thing especially in fps games... input lag is really bad the way they implement it...

Triple buffering doesn't add "really bad" input latency. It adds at most 17ms, though as I said, you can use a FPS cap if you don't want v-sync at all with RadeonPro, MSI Afterburner or EVGA PrecisionX. I was merely mentioning that v-sync rarely drops your FPS down to 30 FPS like you had said. That is an old school problem, something that rarely exists today.
