Moving my mip mapping slider from 8 to 4 was the best thing I have ever done. Almost all my shimmering was gone. Another thing, depending on your computers capability, is to set a higher anisotropic, supersampling and antialiasing value.

 

I used to use 8x antialiasing and 8x supersampling, along with 16x anisotropic filtering and the results were wonderful.

 

Fortunately now with a better computer and nvidia inspector, I have higher values such as 8xS anti aliasing and 2x sparse grid supersampling along with fs mip mapping at 4, and my results are excellent. No shimmering, no jaggies, and no blurried ground textures (but thats because of some other tweaks as well).

 

However, such high quality settings have a toll on framerates. Lower settings are more than acceptable as we people who still use FS9 mainly have lower hardware, but there are exceptions. I'm able to run FSX but FS2004 in my opinion is a much better sim with all Russian scenery and aeroplanes.

I have a NIVDIA GeForce GTX 275 graphic card, would putting my mip map slide from 8 to 4 benefit me any?

Most likely. :rolleyes: 

 

Remember whilst the GTX275 is no longer state-of-the-art it was still introduced well after FS9 appeared on the scenes. It IS state-of-the-art insofar as FS9 is concerned.  -_-

With my setup I no longer concern myself with monumental frame rates. If I can maintain 30fps and have everything else maxed out I'm happy. 6 cores have made a very big difference to all of my flight sims. My graphics card is more than adequate in all sims and maybe the 4 gig of VM has helped. Probably not.

 

I have some very nice add-ons for fs9: Queen and 737 PMDG. Aeroworx B200 King Air and an old favourite of mine the RAS C172. ATR72 500, Active sky 6.5 and the list goes on...VOZ Scenery etc.

 

I am very stoked though, with the mipmap tweak. That's gold. I am forever in your debt. I have not even looked at the .cfg file yet. Are there any entries necessary to get finer ground detail?

What I ment to say was that I don't have a shimmering problem. What other benefits does moving the mip maps slider lower have?

Performance, even though on modern hardware it's nothing significant. I didn't notice quality reduction at all when moving back my slider.

 

However, at default airports, might happen. But I fly with custom designed airports and airplanes so they're not that affected.

Turn midmap slide to 4 really helps. I also had this problem since moved to a new system and set midmap to full right.

Thank you for this tip!

Hi,

 

does it have a cause that some of you recommend setting the mipmap from 8 strictly to the value 4? I have to admit that I still lack knowledge in these graphics topics. I rather thought that it was a matter of individual setting for every single system. For instance, I found that at my PC mipmap=5 gives a good compromise between shimmering and blurryness particularly within sceneries, while I still have to convert mipmapped AI plane textures to such without mipmaps to avoid blurryness.

 

 

 

FS2004 [...] with all Russian scenery and aeroplanes

johnss1948, my understanding is that multiple cores in fs9 are of no particular benefit since it can only use one of those cores at a time.  I used to pick which of my cores I would use for fs9, but no longer do that.  I would be interested in what others have to say about this.  Processing speed and capacity are still essential. of course.

 

Also, unlike many of you I feel that 60fps is the gold standard for fs9 performance.  Particularly in planes that are virtual cockpit only like some newer payware, the smoothness while panning views is far better at 60 fps.  The whole concept that the human eye cannot see the differance is bogus.  Lower frames are very adequate for enjoyment, but are a compromise nonetheless.

Even 20 fps is smooth for me, but I locked mine at 25 frames.

 

I hear everywhere that FS9 is only able to use one core, but I'm not sure how true that is as whenever I check with my taskmanager, it seems to use all my 4 cores...

Reducing the mipmap slider to 4 doesn't necessarily translate into better FPS, but it does have a positive impact on texture loading times and reducing prolonged blurriness, particularly in the case of photo scenery.  As for FS9 using multiple cores, it will do it but from what I've observed the affinity has to be reset every time you start FS for it to do so effectively.  Mine is set to use both of my cores, but in order for me to see it actually happen, I have to start FS,  then go into task manager and disable one core, click ok, and then go back in and re-enable the core I just disabled.  Then FS9 uses both cores effectively.  If you monitor your CPU core usage as I do, you will see the change quite clearly.  This doesn't make FS9 use more of your CPU however, it only spreads what it does use across the cores, the effective amount of processor resources the sim uses doesn't change.  Hope this clears up some of the questions for you.

 

Cheers,

Jeff

 I'm absolutely over the moon with my fs9 performance since the above tweak and I'm using VOZ scenery. From altitude it looks superb. From 5000ft,OK. 2000ft not so hot. I just want to tighten-up resolution. Does anyone know how to do this?

You're absolutely correct, of course. A trip into SPEEDFAN shows core 0 maxed and the other 5 occasionally registering data. I don't know whether it's the quad channel ram, the socket size or the architecture but this sim is flying and I'm not attempting to be punny.

 

To everyone who's posted in this thread, Thank you for your input, I have re-learned a great deal.
