Those blurries are killing me.

A8VModem: Bluetooth Fax ModemBluetooth DUN ModemBluetooth LAP ModemBluetooth LAP Modem #2I've been tweaking alot my FSX and i'm getting nice framerates everywhere however I get blurries very very often. example : I'm flying at 280 knots at lets say 1000 ft. The textures appears nice and sharp. As I advance there is a distinct line between clear texture and slightly blurry. Then I keep advancing and another distinct line appears between slight blurry texture and the more blurry textures. This keeps happening until I reach VERY VERY blurry texture. If I pause and wait for a minute or two, its crisp again. For this phenomenon to happen (clear to blurry) usually takes about 60 seconds at 250 kts. What I tried to fix the problem :1. Tried to set the terrain texture to 5m, still no avail, it keeps getting blurrier and blurrier.2. Tried to set the Fiber Time Fraction setting to 0.90. Still no avail.3. Tried to limit the FPS to 10. Still no avail }(What I know :1. According to the MemStatus tool, 70% of my video memory is being used when FSX is running, meaning that it isn't overloaded.2. According to the MemStatus tool, only 60% of my RAM is being used, meaning that I have enough RAM.3. There isn't much hard drive activity because the HD led flashes for 1 or 2 milliseconds every 10 seconds. I didn't try a defrag yet, but the defrag tool tells me that my HD is only 10 or 11 fragmented.What I need to know :1. What is causing the problem2. And, HOW DO I FIX IT ?Thanks

Unfortunately, I don't think there's much you can do, aside from buying a faster CPU. I have a similar system (slightly quicker CPU and newer video card) and I also have these problems. I've tweaked and tweaked and tweaked, and I still have blurries. From everything that's been posted, I think most people are in agreement that FSX is seriously CPU bound and those of us with only "adequate" CPU's will struggle with these blurry problems until we upgrade. That being said, there are some people with high end Core2Duo's and Quad-Cores that are experiencing blurries, so there is quite possibly some unresolved problems with the FSX code. I wish I could help you out, but unfortunately I'm stumped too.... What is it?? Misery loves company???cheers

WOW ! I thought that the blurries had to do with the hard drive speed limitations or the video ram or something. I'm sure that there is something wrong with the FSX code. I remember that in FS2002 and FS2004 I wouldn't get blurries even at 600 knots. From what I read on the blogs, the blurry problem is being researched (can someone clarify this ?). I think its something that has to do with the fact that FSX is not calling the scenery to get refreshed. I seems that it loads once for a large area and once you reach that area, it doesn't reload anymore. In FS2002 and FS2004 if I zoomed out very far, I would see blurry texture at the ends. When I moved forward, new textures would load in the front and the ones in the rear get thrown back. Its weird that in FSX when I zoom out all the way, no FPS hit. In FS2002 and FS2004, when I zoomed out all the way, the FPS went down (maybe because its trying to reload some textures)...

I believe Phil Taylor said "we're taking a look at it..." That being said, I wouldn't expect quick resolution. If anything, the DX10 patch due out later this year, may address this problem (or it may not - no one knows). There was a lengthy document posted by Phil on his blog, regarding blurries and 3D graphics in general. Unfortunately, I don't have the link handy right now - there is a post containing the link somewhere in the FSX forums....cheers

I remember that there was a 5 page thread about the Type 1 and 2 blurries (the ones I am experiencing). It seems that they are 'investigating'. I also read the blurry type 3 (filtering issue) PDF, that's not what I'm experiencing. Also, I've seen that many people that were saying that blurries are being caused by the fact that the computer being overloaded, but the memstatus tool shows otherwise. I've seen on the long 5 page thread about the type 1/2 blurries a user that had a very very powerful system (Core 2 Duo, 8800GTX and 4GB RAM) who put all his slider to the left except the texture terrain slider set to 1m. He was still experiencing blurries. Apparently, blurring didn't happen in FSX RTM, I can't really remember but I'm sure that there is something with new way that FSX SP1 handles textures. I hope that they get it fixed really soon. I don't want to go back to FS2004 or switch to X-Plane for my 'flying' fix.

Yeah... I thought I tweaked it and brought it to a reasonable level. and yesterday..I flew from Denver to Aspen to experience the very nice Aerosoft's Aspen airport scenery.... and I was having around 19FPS and as I came close to the airport to land.. It was a blurry mess. Messed up a nice airport scenery and approach. I would rather have had 10FPS at that point in time without the blurries (Pre SP1). Blurries for FPS is way too high price to pay.One of the reason I wanted extra FPS is so I can fly faster close to the ground and not worry about blurries when using Photo sceneries. Oh wellMAnny

The question I'm asking myself is why is the texture swapping in FSX so so so so slow. In older versions of Flight Simulator it was nearly instant, never saw such a blurry mess. No other Flight Simulator has that problem; X-Plane, FlightGear and so on... I really think that M$ should reject the whole idea of texture swapping or at least make it faster. I remember in FS98, I would slew at like 20000 knots and not a single blur (and that was on a medium end system at the time). Right now, I assigned the refresh scenery to tab+s to reload the scenery when I see a blurry mess. By the way, is anyone not experiencing blurries even at high speeds (make sure you know what they are in the first place). What kind of specs do you have ? What kind of tweaks did you use ? What are your settings ?Hope this gets fixed soon, I really want to enjoy FSX as I used to enjoy all the previous Flight Simulator version. Clear ground and beautiful smoothness. Lets all hope that THE MAGIC TWEAK FIX THING or another patch comes around soon !

Tried to limit the FPS to 10. Still no avail Hmm... Which virus scanner do you use ? I changed from Avast to the Microsoft LiveOneCare 90 days trial and FSX loads and runs now much better. It looks like this program leaves the sim completely alone.The best performance regarding texture loading you'll get (IMO) with FSX on an own hard drive where the files are placed on the outer tracks. Defrag those with the O&O (trail version) by file name. It was such an improvement that i purchased O&O.Maybe not the silver bullet, but worth a try. It works great for me. And yes, your CPU is a bottle neck with FSX...Heiko

Is this even possible to predetermine the actual sectors?BTW, thanks for the 0&0 suggestion Heiko, I will give it a try. :-)

Sorry for the confusion... :) I meant when you use a hard drive only for FSX (with nothing else on) the files will be placed automatically on the outer, faster tracks. When you are using only one hard disk for everything - with Ultimate Defrag you can specify which files you want to place outside. I purchased both, Ultimate Defrag and O&O, but like i said, the best result i get with a separate FSX only HDD and a O&O defrag by filename. Heiko

I am at the moment using Tile Proxy with a cfg supplied by the author and I do not get blurries and only an occaisional stutter.HOWEVER before turning to TP I like everyone else was suffering from blurries and like everyone else tweaked untill I was all tweaked out, my head was done.I asked myself the question if the tweaks did not work why have them?I deleted the cfg and allowed FSX to rebuild a new one.I then inserted DisablePreload=1 and set my Tex Max Load to 1024 and nothing else and guess what NO BLURRIES.So there may well be a case for some of us NOT to add these alleged magical tweaks, try without.I too am concerned about my CPU being inadequate and am going to get an Athlon 64 4800 dual core [which is compatible with my motherboard]My System [in brief]ASUS A8N-E M/BAthlon 64 3200+ [overclocked by 10% running at 2200]Ati RX800 TD256E Graphics Card3GB of RAMRegardsRichard

Can you try the fsx.cfg file that I am attaching as text attachment to this posting? All you need to change back is the screen resolution and size to match your graphics card and maybe adjust some of the graphics settings to your liking.With this fsx.cfg file my flight sim loads several hundred tiles per second during flight (as measured by the Tileproxy application). I know that only when the sim loads a lot of terrain tiles per second it actually has a chance to keep up with the aircraft graphically.There are a few fsx.cfg files out there which result in terrible terrain loading performance. But I don't yet know which statement in these files triggers this behavior.Christian

WOW ! Your cfg helped my blurries alot. At 240kts, I can see the textures loading in front on me. Much much much better than the texture taking ages to load up. Maybe we can find the statement you are talking about and increase it even more... !EDIT : I did some more research and here is what I discovery. The texture get blurry and then load up. Blurry and then load up. When suddenly, FSX suddenly gives up and doesn't refresh anymore. It seems to be the more I increase the Detail Radius, the later it 'gives up'. Hmm.. maybe there is some bug...

Okay, this "pumping" between bluriness and crisp textures appears to becaused by FSX periodically spending a lot of time updating terrain near the horizon. While it is dealing with the terrain in the distance (which may have just moved into the visual range), it doesn't have any time to update the terrain around the aircraft.If I had designed the FSX, I would have implemented two concurrent texture jobs. One that updates the stuff close to the aircraft permanently and another thread dealing with new terrain that has moved into the visual range. Right now it seems the sim is doing these jobs one after the other, causing a temporary loss of fidelity near the aircraft while it is busy loading the new terrain.

For those who want to see the phenoemenon happening, Here is a flight in which you extract its contents into the My DocumentsFlight Simulator X Files folder.(http://www.mediafire.com/?ebsjxzbhzx1) Just simply press up a couple of times until you reach 320 knots (its already in slew mode). Then you will see the ground textures clear in the beginning. Then getting blurry and attempting to clear itself. And finaly it will give up. I think the problem is that FSX is overloading itself with attempts to refresh scenery. Maybe some developer can shed some light on this problem. For those who don't see any blurry textures even after 5 mins of flight. PLEASE tell us your specs, cfg tweaks, other tweaks and settings.Thanks again EDIT : I did even more research. The blurries seem to happen much sooner in cities than in rural areas like Friday Harbor. In the rural areas they are pretty rare. However in detailed cities like Chicago, the blurries happen in about 30 seconds at 240 knots. There must some inefficiency in the texture system. In other Flight Simulators the textures switch instantly. While in FSX, it takes a long long time. Maybe FSX is having trouble calling the textures or its doing to many calls at the same time and is overloading itself. It obvious that isnt the computer that is the problem because even people with very powerful computers (Latest Core2Duo, 8800GTX, 4GB RAM) have blurries. The devs really need to wake up and see whats wrong with textures. Espically post sp1

There seems to be a second process at work... Once FSX gets behind in updating the textures close to the aircraft, it takes a LOOOONG time for it to catch up. Even if you hit the pause button and the aircraft is no longer moving, it can take up to 20 seconds for the nearby tiles to un-blur and crisp up.20 seconds is an eternity in computer terms, so something has gotten really out of kilter... it is more than priority allocation... it also seems like some stacks overflowing and the cleanup routines taking forever to recover.

I would agree that well tuned disk drives are a good thing and will contribute to overall performance, especially stutters when a lot of texture data has to be loaded. This particular blurry issue, however, seems not to be disk access bound. The nearby blurries can occur and then resolve themselves without any noticeable disk activity, so I would be tempted to believe that this is a CPU/software issue, not a disk bottleneck.

I'm sorry Larry but he specifcaly asked those with no blurries to react. As we all know from your frequently posted screenshots you do have the occasional blurry.

I tried your config file, but it is actually worse than my standard config. Not only that, but your config has a 15 fps cap which is insufficient to hand fly the plane... sooo back to my standard config at 20 fps. {JOBSCHEDULER}AffinityMask=1 // Single core CPU *************{Display}BLOOM_EFFECTS=0SKINNED_ANIMATIONS=1TEXTURE_BANDWIDTH_MULT=40UPPER_FRAMERATE_LIMIT=20WideViewAspect=False{Main}FIBER_FRAME_TIME_FRACTION=.34 // TWEAK 2 ***********{TERRAIN}LOD_RADIUS=4.500000MESH_COMPLEXITY=60MESH_RESOLUTION=20TEXTURE_RESOLUTION=24AUTOGEN_DENSITY=0DETAIL_TEXTURE=1WATER_EFFECTS=4

Based on my experience to date, the cause of the problem is the 280 kts.. On my system at least the texture system can barely keep up at 120 kts.How to fix it is the $64,000 question to which no one has yet provided an answer.I would suggest turning off autogen and if you have an AGP video card, set the BIOS to 256MB AGP aperture.
