Possible to gobally cap FPS?

Can't downspeed the card, because making it do 30fps in open country would make it do 10fps in cities.
Can't turn AA or Aif up any further, game absolutely requires them, so can't turn them off either.
I ran Doom3 with the vsync on and ludicrous settings and it behaved exactly as described above, either doing 60 OR 30 (or even 20) never an inbetween value. Other games don't, (this is using their internal FPS meter, I will try FRAPS).

I think this is a question of semantics, jumping between 30 and 60 in such a way as to give 55, as you describe, would cause the exact thing I've been talking about. This is somewhat backed up by the "stutter" having the exact same frequency as the difference between the displayed framerate and the nearest VBL locked speed. Ie, 55 FPS flicks at 5Hz, 58FPS at 2Hz, 45, looks OK because the flick is 15Hz.


I think vsync off is all I can do for TrainSim. The driving games are not ruined by this, and shooters are unaffected it seems. The only other game I MUST run without vsync is GPLegends, which wont work online if it cannot run at precisely 36fps.
 
Something not right about your doom3 results. I fired it up not so long ago just to see how it runs on todays modern platform and I was consistantly getting fps in excess of 60 fps so with vsync on you should never have dropped below 60 fps. :confused:

Again, it depends what you throw on.

play the RoE expansion with AA enabled, and you might see framerate drops into the 20-30 region.
 
im pretty sure DX has an inbuilt global limit...

start; run; dxdiag

click the more help tab and "override"
enter the refresh here and see what happens...
 
I agree with the OP having the option of a 30FPS limit would be loverly, having played games like halo on PC and console (pc version has a 30FPS lock inccidently so it's not hard to do) the worst situation in terms of smoothness is an unstable frame rate

On my PC i could run it constant 60FPS and it's very smooth, however when i played on Xbox while it was not as responsive as my PC it was still very playable, and i quickly got used to the new level of responsiveness bought about by the 30 FPS drop, the trouble with a frame rate jumping all over the shop is the games responsiveness level is constantly changing so you never seem to get the same feel or smoothness of control as when the Frame rate is locked solid be it at 30 or 60 FPS

Ultra settings, 1680x1050, 16QxAA 16xAiF.

But I thought it was kinda low myself, and you should see the state of Quake4.

At the same time, the machine is pulling 45-50 on Crysis in the "dx9 hotlist" spec, 200K in aquamark and 7000 in Vantage, so it's no slouch. Must just be ID-phobic or something.

Hmm maybe not as bad as I thought then. I find 16Qxaa is a framerate killer. The Witcher runs at 8-15 fps with that switched on yet at a more reasonable 2xaa I get 55-110 fps with 16xaf on both. So even an old game like doom3 might be crippled by the 16qxaa?


According to Toms Hardware and with a lesser cpu at 1600 x1200 4xaa, 8xaf you should be getting 113 fps. Does 16aa/af really kill the framerate that much?

http://www.tomshardware.com/charts/...,1633,1604,1575,1630,1620,1629,1625,1623,1621

And if it does, can you honestly tell the difference between 16xaa and 8xaa?
 
Oh no, you can't tell it at all in a game like Doom3. In fact it's all just set that way at the minute for the benefit of MSTS (all those parallell and near parrallell lines are aliasing city, and the track bed, being a constant texture running from under your nose to infinity is a prime candidate for AiF).
Also using what nhancer calls "32x" but I think it's really what NV calls 16Q.

Funny enough Aquamark still score really highly with all that guff on, until you engage the "supersampling transparency AA" thing, at which point the "large scale vegetation" test chokes down to about 12fps and ruins the whole score.

In general I get away with them being on in most games, it's only smoke/clouds/particles that lose the plot usually.
Starting to use nhancer to set the right levels for each game.

I do have a driving (I think) game that offers vsyn at half rate, which would be ideal....but it's only one game, and it goes up in a big ball of fail if you switch it on anyway :(
