P3D v2.5...Does anyone use DSR?

Recommended Posts

Hi all,

 

I have finished re-installing my addons on the new Prepar3D v2.5 (except ASN and ORBX) and I am in the process of finding again the 'sweet spot' of performance and anti-aliasing. Its a pity that in this wonderful simulator we don't have a perfect in-game anti-aliasing and we need to find external settings to modify it.

 

I use the following tweaks in my  p3d.cfg :

 

UseGlobalTerrainView=True

SHADER_CACHE_VERSION=1

FIBER_FRAME_TIME_FRACTION=0.01

 

Altering the graphics settings inside P3D does not seem to have a significant impact on performance.

 

Frame limiter: Unlimited frames (better FPS and using TrackIR)

Vsync: ON
Triple Buffering: ON

AI Traffic: OFF

 

For anti-aliasing I am mainly between two settings mode:

 

1) Nvidia Inspector = default setting
    Nvidia Control Panel = DSR:4x       

    P3D settings: 4x anti-aliasing and no FXAA

 

2) Nvidia Control Panel = default 

    Nvidia Inspector = file from this source: http://simtweak.com/ (uses 4x anti-aliasing and 4x transparency anti-aliasing)

    P3D settings: 4x anti-aliasing and no FXAA

 

 

The best image quality is definitely using the 1st option (DSR), however I am not sure if it is placebo effect or not that the 2nd option is giving better performance. That's why I would be glad for your recommendation. 

I have also visited Rob Ainscough's website but haven't find a ''best'' setting for the latest v2.4 or v2.5.

So, my question is maybe the following..do you still use DSR ? 

 

Maybe we can run a poll with the following to choose from :

 

1) DSR 

2) Vanilla Nvidia Inspector/Control Panel

3) AA using Nvidia Inspector/Control Panel

With P3D 2.5 I am using 4x DSR with no AA in P3D. In version 2.4 this would have caused a lot of shimmering however with 2.5 the shimmering is virtually gone and the quality is excellent! It also gives me great performance since there is no need for AA. I am not using Inspector or the Control Panel. Everything is default except for FSDT and Flightbeam airports. Also flying the Eaglesoft Citation X with Opus Weather.

Hi thetford569,

 

did you just happen to install the most recent Nvidia driver in parallel? I am still under 2.4 and updated to the most recent driver and it's my impression shimmering is much improved in 2.4 already. Thus I would like to isolate the effects from P3D2.5, from the latest Driver, or, perhaps, just from a clean installation.

 

Thanks and kind regards, Michael

Thank you, found it in Global Settings, where I seldom venture.  In my case it doesn't appear neither in game specific settings nor NI.  I have to give it a try.

Thank you for your replies...

 

thetford, I tried your setting and it seems promising. However then I tried with heavy cloud conditions and there was stutters.

The best solution for this situation seems to be default Nvidia settings  and using 4x anti-aliasing inside P3D (even using FXAA).

I am not using the latest drivers....can't remember which ones I am using off hand. I have not had issues with stutters but I am using Opus Weather right now until Active Sky Next is working with 2.5.

Hello,

 

it would be really interesting to know which driver you are using.

With DSR 4x, but without AA filters, the shimmering and flickering are tremendous, in 2.5 like in 2.4.

Same here..Opus until ASN arrives (in 1-2 days hopefully as announced) .

 

Brandon, I used the latest Nvidia drivers, and DSR 4x without P3D anti-aliasing is giving excellent results (no shimmering, except a slight shimmering on the horizon). I used the ''gray & rainy'' weather theme using only DSR 4x and was not smooth. Instead when used 4x P3D anti-aliasing without DSR it was very smooth (but not as good in anti-aliasing terms).

I tried DSR but turned it off after an app error with Visual C++ module... maybe coincidence but DSR was only variable that changed.  Meanwhile, I'll just sit on the sidelines of this one.

Ok I just had a chance to check my settings while I am flying this morning. I am using the 344.75 driver version on my GTX970. I thought I was using no AA but in fact I am using 2X AA inside P3D. I am not using Nvidia Inspector and inside the NVidia Control Panel I am only using the single display mode and texture quality high options. There is some slight shimmering with very distant objects but this is my best balance between too much shimmering and bad performance. If I use 4x AA the frame rate starts to tank.

 

I just departed FSDT KDFW in the Eaglesoft Citation X with 70% AI Traffic from UT2 using Opus Weather and REX and the sun was smooth with frames never below 20-25. I know this will go downhill some more as I add Orbx stuff back in as well as Active Sky Next but right now this is great and better than 2.4 was.

 

I really am only having problems with OOMs in Prepar3D and otherwise I am getting great performance and image quality. I have not gotten an OOM with 2.5 yet but I also don't have Global, Vector, or UTUSA ver 2 installed yet. I fully expect to have to dial some of my settings back down when I get those installed. Right now I'm ending with about 500-600 MB of VAS flying between detailed airports but again I'm only using the default terrain. We will see how it goes....LOD is a big factor and I have it at Ultra now. Hopefully I can go down only 2 notches and be ok and not be back in OOM land like I was with 2.4

On the default airport and default weather, with complex aircraft, I get nearly 60fps when I use only P3D anti-aliasing. However, same settings on the new Fly Tampa's Toronto airport I get 20-25 fps.

 

The fact is that I can't stand the shimmering of the P3D's anti-aliasing and the blurriness of the P3D's FXAA.

Still the best image quality is using DSR 4x...

Did you try the most recent Nvidia driver? 

 

I am still using P3D2.4 but upgraded to the most recent driver 347.72 recently. I had terrible shimmering before only to be cured using 4xSGSS via NI. This seems to have gone now. There are still aliasing issues with some houses' facades and a few taxi lines, but no more disturbing shimmering. This was a clean driver installation with no new NI profile activated.

 

I know this would be too good to be true, thus I would learn if others can confirm or deny this observation (after all I could have made some configuration change I overlooked).

 

Kind regards, Michael

Hello Michael,

 

Thanks for your suggestion. Yes, I am using the latest nvidia driver on a clean installation. I maybe agree with you that it seems better from the previous versions (I don't know if it's the P3D update or the Nvidia that contributes here) but maybe it is the comparison that drives me..For example using P3D's anti-aliasing I see shimmering on the aircraft's exterior painting lines...while using DSR it is picture perfect clear.

 

Kind regards,

Ifikratis

 

 

EDIT: Ok, I now got very good image quality results using all P3D anti-aliasing settings (4x, 16x and FXAA on). Again DSR wins, but now its much closer.

I am using 347.52,and cannot seem to be able to turn on DSR,could someone please share their global settings?

Edit, I am running 2 780 ti cards in SLI,with just the graphic driver,no experience.

This - how does one enable DSR in P3D?

Its done in the driver global settings,by right clicking desktop. I have the dropdown,but the only choice is off.

That's weird...I suppose your GPU is supported. There is a list of supported GPUs here: http://www.geforce.com/hardware/technology/dsr/supported-gpus

 

Else, I would try a clean re-installation. 

 

Using DSR 4x, its close to real-life experience clarity for me...There must be found a way to use this technology with minimum performance cost.

I can confirm DSR does work in the 347.52 driver. Although I am not too happy with the effect, I tried it several times before but never was. At first, it has a noticeable performance impact (slower texture loading and fps, albeit not as hard as 4xSGSS, and the simulator seems to be less smooth) and it does not completely cure (but improve) the shimmering houses' facades.

 

It think it's my combination of screen + graphics adapter. I have a ~3K widescreen monitor (34", 3440x1440) and a comparably weak GPU (EVGA GTX 760 4 GB, factory overclocked though). While the GPU manages native resolution quite well, it comes to the margin (i.e. close to 100 % usage) using 4x SGSS or high DSR settings in "hard" environments, but is better in handling 4xSGSS.

 

Kind regards, Michael

I think that the DSR does not work in SLI mode.

 

Edit @ Michael

 

I think that the shimmering of the facades is not totally solved in any way.

I tried even with DSR 4x and 8x SGSS (no clouds).

That is a bug in the NVidia CP. Go to your Windows Control Panel - mouse settings - Pointer Options Tab and make sure "Snap to: Automatically move pointer to the default button in a dialog box" is UNCHECKED.

Thanks for the tip,turned up to max,doesn't seem to work in my setup.

I'm assuming you know this but just in case. When you're in the sim, alt+enter twice. If your red info text is now tiny, you've got DSR!

Still no go for me.
