1: how to do it?

2 Working link this one is not working

3: Without 1 and2 no tweak.

 

Thank you for no tweak......

Sorry to sound ignorant, but where is the benefit over downsampling via custom resolution?

 

What DSR does is nothing else, except it only ever gives you one downsampling resolution at a time depending on your scaling factor. Via custom resolution you can have multiple and switch them ingame without constantly changing the DRS setting in the control panel.

 

Furthermore the DSR factor often leads to very bad resolutions. A factor of 2x for example is exceptionally bad because it creates a resolution that has 1.415 times the height and width of your native one. Couple that with the smoothing of DSR and all you're doing is blurring the crap out of the image. A proper downsampling factor would be 2.25 (1.5*1.5) or 4.0 (2.0*2.0). Instead of smoothing one should rather use the NVIDIA FXAA option as it does not blur as badly as the DSR smoothing.

 

So would you please enlighten me why you would want to use DSR with a totally iffy resolution and blur when you can achieve a better result by creating a custom resolution (2880x1620 on a monitor with 1920x1080 native res) and adding conventional MSAA/SGSSAA ontop.

 

On thing DSR could be useful is for combining it with custom resolutions - if DSR allows for that. You could create a custom res of 3840x2160 (4K) on a monitor with 1920x1080 native and use DSR with a factor of 4.00 on top with no smoothing. That would clean things up and sharpen things nicely. But I doubt even SLI setups would be powerful enough for that effective 16K res. And menus would be unreadably small.

For P3D, because it only runs in windowed mode or hybrid fullscreen (still a window), you have to set your desktop resolution to the new DSR resolution option.

 

As far as I can tell, the resolution setting within P3D is irrelevant.

 

Running P3D in fullscreen mode does work with DSR, and you do not need to set your desktop to the same resolution.

 

I'm running P3Dv2.4 and am selecting the new res directly from in the sim.. you do need to you drop in to windowed mode and back to make it change though... or, restart the sim.

 

 

 

except it only ever gives you one downsampling resolution at a time depending on your scaling factor.

 

It you tick them all, you get all those new resolutions in the display options, not just one at a time.

 

I have been downsampling for years, but DSR gives me better, cleaner results.

 I then will move back to my proper driver suite...but for now...WOW!

 

 

This isn't directed at Mitch, but just a word of caution to anybody following this thread. Just be careful. You will need to uninstall the laptop driver and then use a driver cleaner, before reinstalling a new desktop driver version (ala reverse of Rich's installation procedure for the 344.24 mobile driver set). The laptop drivers leave around a bunch of files that will cause your system to be in a permanent mess.

I had no such issues (I dropped back to my previous driver to test something) I did however chose the 'custom' install, and only install the display driver. Letting the package (express) install everything, may add junk you don't need.

Just to go back to what I have said - I do not change my resolution in P3D - I leave it at my native resolution 2560 x 1440 - have no issues with menus looking bad nor my desktop - hence leave your windows native resolution alone in my case anyway - maybe this is just a better driver than any others I have tried - smooth as butter and more fps so maybe DSR is doing nothing for me but it does look better and performs awesome so I am not questioning it just yet - seeing a few complaints about blurry menus and such dont change your resolutions and just turn on DSR and see what you think - thanks

Or use the system restore. Thats how I went back to my regular driver suite. It was worth a try, but in my case I had some additional issues (see above).

 

Harry

Or use the system restore.

 

Yep, that assures that nothing nasty will be left "laying around". I've alway been a bit leery of those driver cleaner utilities myself. As Novation wrote above, one might be able to get away with just a normal driver install over the top of the laptop driver, depending on how you do the install. The problem is that even just a simple driver install, the laptop driver installs files that the desktop driver package can't uninstall, because it doesn't know about them. Thats what the various INF files tell the installer to do.

 

 

so maybe DSR is doing nothing for me

 

We seem to be running the same topic over two threads, and I've just said much the same in the other one... but, no DSR will be doing nothing, as the main point of it is to allow you to select a resolution higher than your native, as you know. The only thing you may see, if enabled is the effect of the Smoothing.

 

I can't understand going to the trouble of adding these drivers, but not testing the higher resolutions it offers, and the affect it has.

 

Not having a go Richard, just curious :smile:

Yeah exactly why in the world add modded .inf files and force your perfectly running system into lala land just so you can make your card work harder but have the end result the same resolution?

 

If you want your card to work harder, then simply add in a customized resolution and run the sim at that resolution.  The pros is that you are now running your sim at a higher resolution so you get better details, crisper image, etc.. if your monitor can handle it.  The cons of course are small fonts and menus.  Today's graphics cards are generally not being pushed to their resolution limits, especially 1920x1080... Just about any modern card can handle that  and can be pushed farther with little loss in FPS. 

 

I guess I need to show the difference.  This is a distant mountain scene and I zoomed the cropped pic by 500% to show the details you are missing by flying at a lower rez:

 

1920x1080

 

 

2560x1440

 

 

Now if you take a DSR image to 2560x1440 or even 3200x1800, and then downsample it, there is no way you're going to achieve the same level of detail as simply running the sim in the higher rez.  It is mathematically impossible.  Yet your card is going to work just as hard doing DSR as it would to just simply run it at the higher res.

 

One thing I've learned over the years with video cards and drivers, there is no magic bullet.  A fast card is a fast card and good drivers are good drivers.  This DSR is just a tweak that allows people to keep their resolution the same while achieving some subtle visual benefits of running at higher res.   For me, I'll just run it at the much crisper 2560x1440x32 as I have been for over a year now..

Ok tried sampling only in P3D menu changed resolution to 2804 x 1577 it was the only higher option I had picture quality was better and fps a tad better so this may be a keeper - kind of reminds me of sweetfx - where you see a bit of blurry menu text but no biggie - thanks Novation

Hey Rich - great find although haven't had the time to try it out as yet...

 

A question, my setup is currently 2 x 27" monitors linked together so seen as one monitor running 3840x1080...and under those, 2 more 18" monitors ..so 3 all up...

 

If i tried this, what resolution would i use? I guess it would affect all monitors as well? Could well be its not for multiple monitor use?

 

Thanks for your help matey

Hi Doug - check out this - might help as I am not sure - seems its for windows 8 so might have to search around

Posted by Mark - He found this tweak

 

Hi Harry... just to check; don't run DSR at a higher resolution for your desktop, only set the new resolutions within the sim [swap between Fullscreen to Windowed and back to apply in P3D]. Maybe Win8 has some issues with it though... I am on Win7 and don't have cursor or menu issues, apart from menus getting smaller as the res goes higher.

 

For whatever reason I get better performance, and visuals, running a much higher DSR than better modes of AA.

As already been mentioned, this is essentially downsampling / SGSS

 

What would be interesting IMO is to see a performance comparison between DSR & SGSS in 2 or more 8/8 overcast cloud layers. Anyone willing to give it a try? Theoretically both should perform the same provided that both are 2x2x (3840x2160 to 1920x1080)

I'm at 3840x2160 and you can tell the difference. I am using teh 337 and the instrument text is a little clearer. Really not much of a difference. I am using zero aa inside the sim but 25% smoothing on the DSR. I have to go into windowed mode to change anything because All of the UI Text is tiny LOL

Seen some posts about the resolution outside of p3d. I did nothing with my desktop resolution, just the resolution inside p3d. It only works in full screen mode for me. Since all the UI elements from the menu are to small to read, I just alt-enter to go to windowed mode and all is back to native resolution. Again no aa set in p3d but the aa looks nice by setting the dsr smoothing to 25%. Not bad.

Still think I am getting a little more of the micro-stutter, but not sure.
