Stutters?

***PRB*** · August 23rd, 2010, 17:11

Is there a quick answer to what causes stutters? I have 8 GB of fast RAM, for heaven's sake, a fast 8 core processor? Why the heck am I stuttering?

Iam no expert in computers, far from it. What I have read about stutters is that the processor is feeding more info to the vid card, than the vid card can handle. Also I have experienced some stutter in very hot room temps. As to a cure, there are many mods to FS, vid card, CFG, computer settings. I have only tried some of these. I can run default FSX at max display settings, set at 30fps with no stutters, very smooth, except for a couple of areas. I think detailed scenery is the killer. With PNW scenery, I set frames to unlimited and is very smooth.

Paul according to Phil FSX is set up to address all 8 cores however you have to tune them to work. I would take a trip over to Nick N's site and follow his guide. I just build a six core i7980 for a guy who uses his at a flight school and when I went to see him yesterday he showed me how incredible FSX and X-Plane were working on his computer I built. I wish I had copied his config file for you. I will try to call him and see how he set up his config file. I know he said something about a tool similar to alacrity to manipulate his cores. I assume you are using dual Xeons is that correct?

You may be able to loose that also with a TBM tweak...

texture Bandwidth Multiplier in the FSX Config...Its default at 40...Try...10...the 60 70 80

Give each a good 10 minutes test ..

Turning off search indexing (in Win7) also cured most of my micro-stutters.

How do you do that ?

Go to control panel, programs and features, in the top left click turn windows features on/off, a list will come up, uncheck indexing service. Great thing about Win 7, you can turn things off without deleting them.

TEXTURE_BANDWIDTH_MULT was 30 on my system. I set it to 10, and flew around. I think it's better. I'll leave it there a whiel to get a better feel, then slowly go through the other values. I just now turned off indexing for the FS drive. As soon as its done "un-indexing" I'll go for another test flight. Thanks for the tips!
