Hello all. I have a strange problem that just started occuring. About every 3 to 4 seconds, FS will "skip", a short stutter. I have not added any new add-ons recently. I've updated all my drivers, defragmented my HD, deleted FS9.cfg, everything I could rule out. I really don't want to re-install everying, I have a lot of add-ons. Any help would be greatly appreciated! Thanks, Dana.

most likely one of your add-ons (probably scenery) contains very high-res textures.The stutters comes from your video card swapping textures in and out (since high-res textures eat up a ton of memory, it needs to dump other textures out in order to load them, thus causing stutters). If you are getting good fps, but experiencing stuttering, then i'm pretty sure the textures are the cause. The hard part is locating which textures. They can be in many places: your root texture folder, the add-on's folder, the scenery folder, etc. I've converted all my textures bigger than 1.4 megs down to DXT3, and my sims runs super smooth (not a single hickup or stutter). I used to get stutters as well...before the texture conversion.-feng

Sounds like a great idea as I have these stutters too.Please advise how to do the conversion.Many thanksToni.

You will get even better performance by converting your scenery textures to DXT1. Scenery nevers uses, nor needs, DXT3, and DXT1 is half the size in kB of DXT3.In fact, even aircraft do not always require DXT3, and many aircraft textures can be better converted to DXT1 - this is valid for those textures that do not have transparencies; otherwise, if they do, then they should be in DXT3.Best regards.Luis

Toni I think there was a thread here at AVSIM about converting your default textures to DXT1. It sounds like a good idea and I will probably do it too.Yak Yak is right when he says it's most likely from the textures. After much study and research, I determined that my stutter was from the texture load/unload sequence, ****and i found that changing Global Texture Size from 'massive' to 'medium' fixed the problem.**** (Global Texture Size is adjusted in Display Settings in FS).I have a 256 meg vid card. I assume, but don't know, that with a 512 meg card, a person might be able to run 'massive' with no stuttering...but I don't know without testing myself.Rhett

Hi all,... and useful discussions about batch converting textures to DXT1 or DXT3 can be found in sticky threads at PAI here: http://www.projectai.com/discuss/index.php?board=48.0Cheers, Holger

There you go. That's the thread at PAI I was thinking of.Rhett
