Further FPS improvements

In my quest for more fps, I stumbled on this:

http://simhq.com/forum/ubbthreads.php/topics/2983182/Re_Forcing_vsync_in_Full_Scree.html#Post2983182

This does seem to give me a good boost, MORE so in black shark than in A-10C but at least it does increase the FPS somewhat but still not at 60.

For nvidia user this should be possible with the normal control panel, AFAIK, you can set the triple buffer there?

I have vsync also on at the moment, because of track ir.

Triple buffer setting in nvidia control panel affects only OpenGL.

CHEERS Taipan.

Works for me ... ATI 5870

(in theory) You will only get an FPS-boost if you had vsync enabled, but Tripple-Buffer disabled before. That's like driving a Porsche in 1st gear, as the new image is only rendered, when the monitor is ready to build a new picture.

Vsync also may make the game look more smoothly, but this is largely because the FPS are limited to fixed parameters:

If you have massively increased FPS with vysnc+TBuffer vs unsync - Tbuffer, I recommend using FRAPS to confirm your findings.

The options for tripple-buffering and for vsync are in the standard driver for nVidia as well.

Hahaa, I spent days investigating it and it actually had its purpose so it appears! :)

A summary of my investigation with all the links:

___________________________________________________________

Vsync and forcing tripple buffering

will a10c support vsync with a 5870 and win 7? dcs black shark does not.

The conclusions [for DCS BS] 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).

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

So stay away from "tripple buffering enforcers". Your only concern is enebling Vsync which is your basic 3D driver damn responsibility and it should do it without a single squeek, If your drivers can't enable Vsync it is only the graphics manufacturer's fault. Go to his forums and start the rants. I'm serious.

 

EDIT:

(...) I only inform about "triple buffering enforcers" but seeking a tool that will force Vsync - feel free to do so if your drivers fail at this.

So all I can say for this particular case with someone's A-10C 'findings' is beware of the placebo :) DCS BS special buffering implementation (?) made D3DOverrider obsolete. I will need a hard proof that the implementation got broken for Warthog and that it will require D3DOverrider again.

And that

Mega-Whoopsie!! Sorry I know I just have both forums open and stupid me went to the wrong tab :doh:

That's some serious research Bucic thanks!

Which x86 executable are you guys adding to D3Doverrider? dcs.exe or launcher.exe

I have played with nHancer endlessy and have not found a majic bullet to bypass dated hardware or bottlenecks, in my case my video card.

Will have to try this tonight. I get some slow downs when I am flying fast near the ground.

Don't forget to make a run with FRAPS on in benchamrking mode. Send me the data files if you want a fast verdict.

Pretty sure V-Sync add's input lag though doesn't it?

Don't forget to make a run with FRAPS on in benchamrking mode. Send me the data files if you want a fast verdict.

FRAPS has a benchmark mode? I have only used it a couple times. I mainly go by seat of the pants. :) I have jettisoned my stores on the ground and get a good 1 full second lag before the explosion images.

Should I run the same mission I suppose? Make a mission that has me on the runway or something. Or is there a benchmark mission already created I could use?

As it was stated before: The engine is not optimized, yet.

So you may put a lot of effort into squeezing the maximum performance out of your PC, but if the software can't use it, yet, you won't benefit much from it.

Of course, if there is a driver-problem, that's a different matter.

Just keep in mind that it's a beta, before you fry your CPUs.

Maybe a little graphics could enlighten the concept I thought. And so came up with the following diagram:

Note: To copy one buffer to another happens "instantly", while writing from the GPU and reading to the screen happens "slowly". Key is that the screen vertical refresh rate is always constant while the GPU produces frames at varying rates. The above are three methods to tie source to output with three different results.

V-sync in a double buffer system works slightly differently than with triple buffering. The & port means a new frame is copied only if the GPU has written a complete frame into its buffer AND the last pixel is output to the screen. Then the buffers are copied and the GPU is activated again to produce the next frame.

Triple buffering eliminates the sleep time of the GPU by allowing input and output operations to run at their own seperate rates. This may cause some frames never to be displayed though.

Just keep in mind that it's a beta, before you fry your CPUs.

Understood. I know. Hopefully everyone remembers that.

It's too early to try and optimize FPS !!

A benchmarking (short) track for DCS BS is available in one of my old posts about vsync (the two links at the bottom of my 'investigation' quoted here). For DCS W - I don't know.

Yes, fraps provides performance data acquisition. Turn it on by ticking the group 6 checkboxes - min max avg and FPS

Then send me the csv files.

NOTES re how a benchmarking track should look like:

Fast and clear vsync operation identification is achieved by using constant camera positions and changing its direction every no less than 5 seconds. Launch your track, switch to F2 external view, set camera looking straight ahead and leave it like that. 5 seconds later - camera to the back. 5 seconds later - camera pointing down, then up, then again few different 5+ second views. After that quit, save your track again (it will now be saved with your modified camera positions) and you got yourself a benchmarking track. A good benchmarking track should consist of 1-2 minute recording with views changed every 5+ seconds.

Then launch frpas, launch the game, load up the track hit the benchmarking shortcut key (FPS indicator should change color) and don't move your mouse nor view keys until it stops.

When posting benchmarking data for vsync test always include your monitor refresh rate in the time of doing the benchmark.

Thanks D3DOverrider with Vsync+Force Triple Buffering really helped the FPS on my ATI5870.

The last time I checked force triple buffering only worked in OpenGL titles and you still get the input lag of normal Vsync.

I don't know you guys, I'm getting pretty decent FPS. accept in the "Nelis static template" mission looking at all those static models brings me down to the lower teens, which is understandable. Every where else is good with all settings maxed, res 1360x768 no driver enhancments except anisotropic filtering x16. guess I have a capable enough PC though.

I love the HDR effect, can't wait for that in BS.

Well I have a 30incher, at 2560x1600 so I'll do anything I can for more FPS including Placebos :megalol:

To be honest I also did some other things like disabling services, cleaning out temp directories etc which may also have helped my performance. So my testing wasn't so scientific. But it's playable now and for that I am happy.

Looks like your PC is pretty much Sierra Hotel. That's a fairly low resolution... I may need to drop mine and see what that does.
