Dear Simmers,

 

I'm having a serious frustrating problem on my sim. When flying and especially i choose the gray and rainy theme ( for testing) I'm having a drop in fps from 60 fps (locked at 60) to 30 fps where you can notice the bad sutters.

I have tried also to lower the resolution of REX clouds from 1024 to 512 and also DTX3 but still the same. I have tried many drivers ( including the latest one 344.75) and even though it is stable I still have the same problem. The only driver that I have tested and I didn't have any stuttering was the 331.58, however as I run the sim in full screen mode, I had noticed a transparent line which was visible at all times while flying ( so I guess it's a faulty driver because on the other drivers this wasn't noticed)

 

My system specs are 

 

Intek I7 2600K Sandy Bridge

 

GTX 770 OC

 

 

I'm also using Nvidia Inspector, and I have the same exact settings on Nick's tutorial running at 8xS ( combined 1x2SS + 4MS)

Vsync - Forced On

Antialiasing Transperancy Multisampling - Disabled

Antialiasing Transperancy Supersampling - Off / Multisampling 

Anisotropic Filtering mode - user defined / off

Anisotropic Filtering setting - x16

 

Any recommended Drivers or solutions?

 

I appreciate any help!

Justin, have you enough space left on your FS HD for the swap file? I always keep 50 GB free.

 

It might also be the VC rain which causes the problem, try putting back the default textures. THe textures are called VCrainxxx and are in the fs9/texture directory.

 

If you are using ASE you can reduce the number of cloud layers. Cloud layers intersecting can lead to stutters. I don't know if REX has this feature.

 

In the NVIDIA system utility or inspector you should also experiment with the AA settings, as not all settings work the same with different drivers.

 

I also recommend to set LOD bias on clamp if you have not done so already.

 

Also run an alpha channel fixer, there might be some textures without alpha channels around - these cause stutters too.

 

You should also reduce mipmaps step by step from within FS and see if that has any effect.

 

Cheers,

Hey Sascha,

 

Thank you for your quick reply. The problem is not just the virtual panel but also the 2D panel. I have tried to delete the fs9 inspector profile and rebuilt a new one, and what I am noticing now is that it is only stuttering from the virtual cockpit ( something which i don't really use often) 

Regarding my HD space I have 700 GB free so I don't think that is the issue :( 

LOD bias is set to clamp too, and now I'm trying to find a good Alpha channel fixer maybe this will help a bit

 

Any recommendations?

 

Thanks and regards,

Justin 

Try switching to 4x AA with 2xSGSS and see if that helps...

can anyone post a print screen of his Inspector settings?

 

Thanks 

Justin

Try the HD clouds by Pablo Diaz.

Try the HD clouds by Pablo Diaz.

Steve

I concur. They are the best clouds and they're free.

 

I'm having a drop in fps from 60 fps (locked at 60) to 30 fps where you can notice the bad sutters.

 

Turn V-Sync OFF.

I agree with the above posters on Vsync.  I don't have tearing in FS9 with Vsync disabled.

AA is also known to hit your fps very hard if the setting is high and you have a lot of clouds.

Try running 8xCSAA for a test.  If your fps/smoothness is improved, then it's the AA.

Guys,

 

I tried to switch off the Vsync from Inspector and I noticed that my sim is more stuttering, Then I switch it on again ( Force On) and came smooth with fps 60 locked, however the issue is always about the REX Overdrive clouds. I also tried the Pablo Diaz HDEv2 but sadly enough it's still the same on cloud stutters. I really don't have any Idea how this is possible in an I7 with a GTX770. Maybe is it recommendable to overclock my CPU?

Not necessary in FS9.  You must have other underlying system issues or your FS9 install is not perfect.

 

Do you have the patch installed ... 9.1?

Have you tried deleting the FS9.cfg file and have the program rebuild it on next startup?

I do have the Fs9.1, however I will try to let fs9,cfg rebuild it's own cfg again

Will let you know.

 

Thank you!

How many cloud layers have you set (if you can in REX?) I use Active Sky Evolution and have set it to 5 Max layers. The more layers you use the more chance of stutters.

Steve

I use the Active Sky evolution with a number of 5 cloud layers. I will check REX,however I used it just to install the sets of clouds.
