Distiler, it not the same thing what V-Sych does, i know when put Vsync on you cannot override your monitor HZ, i'll tryed it in FC2.0. Max FPS60 mut no V-Sync without V-Sync

did you notice any FPS boost with D3Doverider vsync and its DX triple buffer option ? stutter improvement ?

 

Is D3Doverider included in MSI afterburner too?

The triple buffering means that the V-sync no longer forces the frame rate to Division of 60Hz (if that is your refresh rate). So instead of only having 5,10,15,20,30,45, and 60hz as available frame rates Triple buffering allows every thing from 1-60hz. So frame rate changes are fluid and not done in big jumps as with Double buffering.

 

You will notice a big difference between V-sync only and V-sync with triple buffering.

 

The triple Buffering allows V-sync with no frame rate loss essentially.

isn't the the triple buffering of CCC (refer to OGL?) actually working ? (with DX)

Are you completely sure it worked for you? Can you send me a text file from FRAPS benchmark with at least two different FPS values kicking in. Plus your monitor refresh reate of course. I'd appreciate that.

I'll be honest, I just can't tell if it works or not, see the results and judge for yourself.

 

The track used is the Su-25 bomb delivery track, and the only changes were Vsync and Triple Buffering.

 

Refresh Rate is 60hz.

I think its for ATI cards, I don't think nVidia cards suffer the same V-Sync issues

Of course it's not nVidia specific problem. see nHancer website articles (help).

I really tried to make something out of this - the smallest number of data points I have ever seen in a benchmark :)

There are two possibilities:

this bench is useless, make a longer one

Vsync+tripple works in both cases because ~50 is not equal 1/2 of 60

 

 

Again, with such a serie one can come up with more conclusions :P

 

Edit:

Please specify the test configuration. What was the test running time and how many FPS values were recorded per second. It looks like 1 FPS value per second, running time over a minute.

 

Edit:

Tripple buffering works normally only in OpenGL. That's why you need such quirky tools like D3Doverider. It will either work or not. It didn't work for me with DCS as far as I remember.

 

 

Here's my results for 75 Hz ref rate. nVidia control panel Tripple buffering setting will not have any effect so don't even try it.

 

Vsynch_weird_liketripplebuff-1.png

 

As you can clearly see in theory I should get 1/2 * 75 = ~30 FPS as soon as my rig is not able to maintain FPS above 75. This is not the case.

 

The conclusions are:

1. The D3Doverrider did diddle squat for Nate :D

2. DCS appears to have some mysterious solution for Vsync limitations.

I can say with 90% probability that DCS Black Shark uses special Vsync implementation (wait for Vsync ?) that allowes to bypass Vsync limitation re FPS being integer fractions of monitor refresh rate so you don't need any tools for forcing tripple buffering (like D3DOverrider).

It does look that way doesn't it? But don't forget that there is also the render ahead technique favoured by DirectX that could be at play here. It is very Difficult to spot input lag in DCS compared to a First Person Shooter for example.

 

Have a read of this (the Render Ahead stuff is at the end)-> http://www.anandtech.com/show/2794

Edit:- as for the Bench results, I've not done any Benchmarking before, sorry. The Datapoints were the FPS from a track about 70sec long. Fraps was not entirely accurate either, as can be seen from the FPS of 62 in some places.

Nate, to be honest I don't care what the method is. I don't see lag and there is absolutely no reason for BS users not to enable Vsync!

 

I know, sorry if I sounded grumpy/mocking or anything like that. The reason i asked for the benchmark parameters is I haven't done any for a long time myself and I didn't even know what am I looking at. Plus FRAPS doesn't feature any "benchmark parameters" :)

 

Just enjoy it people! Other simmers are not that lucky! :thumbup:

Since I got my new gaming rig I've been trying ALL types of settings. I DO have to use D3DOverrider for Vsync... But I have played around with Triple Buffering in my Catalyst Control Center and on D3D... I haven't noticed a dang difference at all with or without Triple Buffering. I just settled on having it off about 3 days ago. I also turned VSync off for a while and tried to deal with the tearing... But with it off I never saw a jump in framerates. It's good to have conformation from your benchmarks.

 

By the way, should I turn on Catalyst AI or leave it off? I thought I heard a mention that it could cause weird graphic anomolies and such if I left it on while playing BS.

Yes, DCS is a "Vsync ready TM" application and no tools are needed. Even nVidia control panel tripple buffering can be disabled. You just enable the Vsync there and there you go.

 

As for AI - I don't know. I have an nVidia card.

Have been doing exhaustive Benchmarks while looking for stutter/anomalies/popups.

 

 

 

 

 

For me:

  • A.I. off caused slight increase in stutter and tearing, a few extra % fps. Hi/Low made no decernalbe difference in FC2 (some other titles yes).
  • Vsync on/off no discernable difference
  • AA settings yes to stutters. I now use a 4x box or edge not 8x
  • Fullscreen on! Some connection to hi AA settings ( loss of 5-15 % FPS with "off"). Fullscreen off, low AA = no tearing, less stutter. yes a bit confusing.
  • Shadows - All Planar a few % FPS increase
  • Water as low as it will go, not much in FPS except High

PS Vsync wont work with Full Screen enabled!!

Spot on my friend. Those are almost my exact settings. I noticed a significant FPS drop when I cranked up the AA just like you. AF is about the same, I keep it fairly low also. I have to use D3DOveridder for Vsync, because our CCC Vsync simply does not work with it. The screen tearing for me gets pretty intense without it, especially noticeable with TrackIR.

 

I've turned Catalyst A.I. on to advanced and I haven't had any weird stuff happen just yet. But when I changed my sampling mode for AA I ran into some weird stuff with the cockpit. So it stays on the basic setting.

 

As far as water and all that stuff, on DCS I've tweaked all the LUA files for the best.

 

 

One thing the Goat forgot when building his machine was a danged sound card.... I think my lack of a true sound card is causing a good amount of FPS loss due to my processor and board having to deal with all of it. I'll wait until the patch comes out and see if there is a major difference there, if not, I'll be ordering a sound card ASAP. (I'll eventually end up getting one no matter what, but I'm trying to figure out if my current priority should be an extra 4 gigs of DDR3 RAM, taking my system up to 8... Or a sound card... Any suggestions would be nice.) :smilewink:

Hi Goat

 

My impressions is that these days onboard sound is OK unless your a muso.

 

5/10 years back had many a fickle fight with sound drivers. And onboard was shit.

 

4 gigs is plenty or sufficient. My next toy will be a solid state drive, just a small one first.

Forget about extra RAM for DCS BS. 4 GB is more than enough for it and even RAMDISK will fit there in! I recommend affordable Asus Xonar DS or slightly more expensive DX. PCI-E version available of the latter one.

 

AA:

Did you know that certain 8x mode (CSAA) will provide almost the same performance as certain 4x mode (MSAA) and higher quality of course?
