No Triple Buffering?

[Freezy]

hey, i recently enabled V-Sync in RO2 and it seems it is only double-buffered, so if my system can't maintain 60 fps it directly drops to 30 fps, which makes the input rather "gooey".

is there a way to enable Triple Buffering in RO2? i did not find a line in the .inis that looked related to it.

Why not disable Vsync ? or force it thru a software outside the game ? (Override)

 

[Freezy]

v-sync fixes the screen-tearing, that's why it's nice to have, but only if it's triple buffered, because it will introduce inputlag otherwise.

i disabled it after i noticed the double buffering, but if TWI would add triple buffering we would have the best of both worlds, no inputlag AND no screen-tearing.

i'm forcing vsync and triple buffering through the ccc, didn't have any problem with it so far. do you have "onethreadframelag" enabled? it helps if you experience severe fps drops.

I run with V-sync checked and don't have any input lag. The tearing was bugging me so I sacrificed my 70+ framerate for a capped 62 framrate.

As Tixhal says, be sure that you have 'onethreadframelag' checked.

 

[Freezy]

OneFrameThreadLag is enabled, this doesn't prevent frames dropping directly to 30 when my machine can't maintain a steady 60 fps.

forcing triple buffering with the ccc works only for OpenGL and RO2 is a DirectX9 game, so it'll do nothing for it.

just type "stat fps" in the console and you will see your framerate just jumps between 30 fps and 60 fps.

v-sync off for me until TWI implements triple-buffering, even Trine 2 uses it and that's an indie-game with a far smaller budget compared to RO2.

but thanks for your suggestions

Most FPS gamers dont use it, input lag is far more annoying than a little tearing
and no matter how good the vsync is you will get input lag.

 

[Freezy]

v-sync + double buffering = slight inputlag, only 60/n (n={1,2,3,4,5,6,7...}) fps possible (60fps , 30 fps, 20 fps, 15 fps)
CURRENT method used by RO2

v-sync + triple buffering = no inputlag, every fps possible (60 fps, 59 fps, 58 fps, 57 fps, 56 fps, 55 fps, 54 fps, 53 fps, 52 fps, 51 fps, 50 fps, 49 fps,.........)
method RO2 SHOULD use for best experience

I tried it in different games, but it sucks no matter if it theoretically shouldtn or not.

The Vsync in RO2 is much better for me than in other games. I don't notice any inputlag, but in other games it's extreme. And it also depends on your Monitor how much tearing you see.

 

[Floyd]

With RO2 I have no input lag w/ Vsync on either.
(And tearing was more of a b*tch in RO2 than other games. It was distracting so I turned on vsync.)

But then what do I know?

i didn't say you know nothing.

not everybody can afford an

 

[tixhal]

my rig also can't deliver stable 60 fps, but most of the time the drops are to 40-50 fps, not much lower. i don't know why, but i have the full range of fps with vsync...

 

[Machete234]

Maybe you disabled it in your driver so there is actually no vsync when you tick the box in the game options.

 

[Nik21]

with v-sync enabled, a drop to what would be lets say 55 fps gets me straight down to 30 fps and this IS noticable in control-precision.

That's wrong. I can play with 40 or 50 fps with VSync enabled.

 

[tixhal]

i've been using forced vsync for years. i don't mind the input lag, i'm used to it. i just can't stand screen tearing. when i tried all ultra settings, i had 30 fps and less most of the time, not really playable.
freezy, have you tried lowering your graphics settings a bit? maybe the ultra settings are causing the low 30 fps for you.

 

[Freezy]

my settings are all at medium except textures@ultra and occlusion quality@normal. Anti-Aliasing, Motion Blur, Bloom, Light Shafts and Ambient Occlusion are disabled.

seeing the framecounter show for example 47 fps is a problem with how the counter works, it takes the number of frames over a short amount of times and divides it by the time, but the renderer will just jump between 30 fps and 60 fps multiple times a second.

60 fps means one frame is rendered every 16.7 ms
30 fps means one frame is rendered every 33.3 ms

if in one second every even frame gets rendered in 16.7 ms and every odd frame in 33.3 ms, stat fps would show 45 fps.

you can try this by standing in a spot where your fps drop well below 60 and stand there for about 5~10 seconds, then the framecounter will settle for 30 fps.


hopefully after christmas we'll get a dev to answer this for good.

I've put in a triple buffering implementation for testing, but I cannot reproduce the frame rate dip behavior. Since you can replicate this issue, would you be willing to test it out (it will be out in the next patch or the one after that) and let us know if it is working correctly. If all goes well, we'll announce it in the subsequent patch. I'll let you know how to enable it once the patch containing this change goes out.

 

[Freezy]

wow, thanks for taking the time looking into and implementing it, of course i will test it for you once it is out.

I thought that there was a form of tripple buffering implemented within the fps smoothing option in the main menu. If you have that disabled try enabling it.
