Windows 10: Windows seem to have broken anti aliasing in some form severely affecting transparency...

I7700k

Gtx 1080 driver 25.21.14.1634

Windows 10 1803

Samsung odyssey, Oculus rift (both show the same effect



A while back i started to get this jagged edge/shimmer issue after a reinstall . Ive reinstalled lots of different windows and driver versions. Hw changes. Windows 1709 showed some better results on vertical lines but steamVR refuse to work on that version to i cant really check it that only works in the corner on 1803. You will see what i mean in the first video. It is happening in every game also in native WMR


Keep in mind that this is over multiple hardware and the effect is on AMD graphic cards and Nvidia, Ryzen and Intel. All tested on windows 10 1803


This is in VR where the effect is magnified 10 times. With the HMD on the desk or on the head the effect is the same. For all youtube videos the effect will be diminished due to the youtube compressions, nothing i can do about this.

Ive been looking at it and discovered it has to do with some transparency (AA) issue (perhaps in combination with mipmapping) thats not being correctly applied.



Here is from WMR cliff house. Notice the vertical lines on the red window having pixelated edges that are always in motion (some hmd jitter). Oddly the corners are working correctly. These lines were solid and fine in windows 1709. The background shimmer lines and on foliage however is not and was the same for 1709 and 1803

Here is a very good example where it goes from working to not working depending on camera position. It is taken with a gopro trough the lens the the Oculus Rift

From DCS World in the KA50:

Notice the gauges where its mostly visible. Same goes for every knob in the cockpit, the white text and so on. menu text is also affected.

X plane

Now the only way to fix or do a workaround for this is 8x Transparency AA from the Nvidia control panel. Does not work with HDR and/or Deferred shading. Pixel density/ supersampling has little to no effect on the majority. Only when 8x Transparency is enabled does it have a marginal effect. I have never in my life had to enable this before now. I used to be able to fly for example X plane with 2x SSAA or only FXAA. Now i need 8x SSAA + FXAA to get the same for transparency and flicker which tanks the performance to unplayable.


When enabling 8x SS transparency supersampling in control panel/inspector and my sims looks about what they did before. The severe boiling(shimmer feel is greatly reduced (almost gone)




This is DCS World 2.5.3 with only deferred shading available.

Its a little hard to see but things are far better with the transparency AA on, almost gone.

I will say it again so it sinks in. I did not have any issues like this prior to having to reinstall windows fresh after 1809 crippled my system. I have since done 7 reinstalls with litte to no change other than in 1709 where the edges of the box was solid and not crawling black/white. This needs to be properly investigated.

x850 pro not anti aliasing

I've got a 3d Club PCI-e x850 pro. All the drivers are up to date, and all my games have the latest updates installed but no matter what i do it looks as if it isn't anti aliasing. In the ATI control centre i've told it to always anti alias and in games if u bump it up to full it just seems to ignore it. Using power strip it has a force anti aliasing setting aswell and that also didn't seem to change anything. If anyone could suggest anything it would be much appreciated. Is it the hardware malfunctioning or is it a driver/software problem. Once again, any help would be appreciated.

cheers

 

[GTX1080] No Anti Aliasing

So, I tried two games on Linux and Anti Aliasing worked just fine. I'm going to boot into Windows later and see if I can find something.

 

Temp Anti Aliasing

I don't really understand what you're asking or what problems you've had with bf2 but....

as far as i know, temporal anti aliasing works best at higher frame rates because it takes data from different frames and combines then to create a more effective smoothing effect than regular anti aliasing. So if you don't have enough frames to take the extra data from, you'll start to see weird things that don't look good.

It depends on how bf2 is running for you. If you have it set up so you're getting 60+ frames per second consistantly, then turning on temporal anti aliasing would be a good thing because it would give you better image quality than regular anti aliasing.

But if you're getting around 30 fps consistantly, then I don't see how temporal anti aliasing would be a good choice to use...

I think temp. AA is just an eye candy technique.
