Strange flickering dashed lines?

[sichars1968]

Just wondering if anyone has seen this strange phenomenom in XP 10.

When flying in areas with fields I see a strange flickering caused by dashed lines sort of moving between the fields. One area I have seen this is around Sacramento(KSMF), I have attached a screen capture to try and show this.

Has anybody else witnessed this, and do you think it is a graphics driver issue? I am presently using the latest Beta driver from nVidia 290.53, which apart from this seems very good.

Cheers

Hmm, try turing up the AA. just a thought...

[karingka]

Don't think that would help, AA already seems to be turned up quite high telling from how good the cockpit looks. Strange issue, not sure what it is...

I get the same effect on the sides of mountains occasionally

I run AA and AF at 4x which gives good results apart from this.

I have tried both higher and it doesn't fix the problem and doesn't really enhance the visuals any more than both on 4x to justify the hit in performance.

I will see what others post and then maybe file a bug report.

Thanks

Do you have HDR turned on?

[sichars1968]

No

[larjeet]

I do notice this when HDR is on I have found that some of them are rivers and water but others I am not sure.

Hi larjeet

I have filed a bug report on it today, so I will wait and see what comes of it. I don't fly with HDR on because I can't get it to look right, and it causes such a frame hit. What AA setting do you use FXAA?

Cheers

[larjeet]

Yes FXAA the other setting just killed my frame rate

[sichars1968]

Hi larjeet

I have AA and AF set to application controlled in nVidia control panel and set it through X-Plane rendering, do you set any FXAA settings on your graphics card control panel?

Thanks

[larjeet]

I dont believe AMD has FXAA settings .

[larjeet]

I notced that your frame rate is showing at 71+ FPS are you running with Vsync on if not try enableing it . what is the refresh rate of your monitor 60 hz ? if so your frame rate is exeding yor refresh rate and this can cause texture tearing . Also I have noticed that I have flickering lines in the distance but these usualy turn out to be reflections from lakes or rivers in the distance.

Hi Larry

Having read the Developer Blog regrding vsync I don't think it would be the best idea to enable it. As you say my refresh rate is 60Hz and from my understanding the problem is, when enabled if the FPS goes below 60 then you framerate is effectively halved to 30 FPS becuase a frame wouldn't have been rendered in its entirety and therefore would need to be drawn on the nest render.

I may give it a try and I'll let you know what happened.

Cheers

I tried enabling V-Sync and it is smooth to start with but as soon as the framerate goes below 60 it gets lower and lower. Pretty much as Ben explained in the Blog.
