Flickers and Shimmers

[J72]

Hello Everyone-

I know that our endless configurations presents some difficulty in troubleshooting certain issues but I am sincerely hopeful that someone can provide a cure for my flickering trees and textures I have configured nhancer as suggested including clamping Lod but the problem continues.  I am also curious to know if there is a particular video card ( past or present ) and drivers that on most systems has been found to not exhibit these problems.

Thank you greatly for your input.

Using 8xS AA in Nhancer?

AA disabled in FSX?

Enhanced AA DISABLED in Nhancer?

Did you correctly set that up with Global AND Profile as i directed?

There will ALWAYS be some shimmer with crap nvidia.. no way around it but the settings I posted will eliminate most of it

8xS is required

Hello Mr. Needham-

Thank you very much for your reply.  Yes,  I setup as you directed.  By the way,  I would like to thank you for all you have contributed to this hobby.  I have followed your posts on a couple of different forums for quite awhile.  It is obvious that you are very knowledgeable about computers and engineering and it is greatly appreciated. Also,  Gex- nhanced is a wonderful addon.

As far as my situation goes,  I may just be asking for too much clarity in the image I seek I don't remember anything like this in FS9. My trees flicker to the point of truly ruining the experience.  I usually run without autogen for that reason. I even ordered a hd3870 a few months ago hoping that would fix the problem but I still had shimmers and slower framerates too boot. One thing that is quite interesting in my case is that on the 8800 I don't really notice that much difference when clamping or allowing on the Lod. I wonder if something is not sticking?

I would say there is something screwy going on then.. You should not be getting massive shimmers with ATi, or, nvidia if its set up the way I outlined. There is always going to be a small amout of shimmering no matter what you do because of the application and yes, FS9 displayed the same issue unless the Mip Level was set to 4 with ATi. Some Nvidia cards required 4 and some would work fine at 8.

The 3870 has less horsepower than a 8800GTS/X and it is no surprise you would see a frame reduction

I hate shimmers as well and if they were that bad I would not even use FSX because autogen plays a major role in the reality of the product for me.

What montior do you use and what resolution do you run? Is it the highest native resolution of the monitor? If the monitor is CRT instead of LCD, what refresh rate do you run?

[J72]

My monitor is a Hanns G 27.5" 1920x1200. It does use a dvi to hdmi cable as the monitor only has a hdmi input. 1920x1200 is native for this monitor. I am on Windows XP as well.

Autogen is certainly important for me as well. I hope I am just missing something simple. If everything is properly set up do ati cards not have this issue?

OK so which card are you currently running? The one in the list above, the GTS?

are your FSX graphic settings 1920x1200x32 with the Global texture Resolution at 100%?

What is the texture resolution set to in FSX?

have you verified these Nhancer settings are both GLOBAL and PROFILE for FSX, and you have verified "Enhanced AA in-game" is disabled?

Have you tried the 174.70's? You can find them at http://www.laptopvideo2go.com/forum/ind ... owforum=66

Also, Nhancer has a new beta and it eliminates the need for duplicate profiles... try it here:http://forum.nhancer.com/showthread.php?t=269

[J72]

Yes,  the GTS. Settings are 1920x1200x32 global texture 100%.

I edited my post as you were posting... check the above

[J72]

Texture resolution is set to 7cm.

One option to check the DVI to HDMI would be to switch to a VGA... using the VGA to DVI converter see if the same result occurs although the image quality will probably suffer.

Make sure the monitor sharp features are not cranked up (OSD Menu) Some LCD's require a bit of tuning in the OSD menu.


You should not be getting massive flickers if the Nvidia card is set up correctly. Also, with the new Nhancer, 8xS is found under COMBINED instead of SUPERSAMPLE

You will never get rid of all flickers from autogen trees.. I can tell you that right now. You may simply be too critical of what you are seeing. Does the flicker get worse if you set Nhancer to APPLICATION and set FSX to control AA or does it remain the same?

You should easily see the difference between 8xS and APPLICATION CONTROLLED, no doubt about that

[NickN]

To be quite honest.. all the drivers display the same with the settings I provided so I dont think changing them is going to make flickers different

[J72]

Interesting...so the dvi to hdmi could be the culprit. I will try your suggestion.

[NickN]

thats what I am wondering as well at this point

If the check with the VGA nets no result.. do you have another monitor you could use as a control to check this out because from your description it appears to me the settings are working, by the way,... forget messing with them because what I posted most likely you will NEVER get better than those values

[J72]

Yes, I have a 1600x1200 lcd I can try.

Thank you for your patience and help.

I assume you do have WideViewAspect=True enabled in the FSX config file?
