Horizon photo scenery still blurring with high end pc

Recommended Posts

Hi everyone , I recently built a new pc for fsx , i7 3770 ivy bridge professionally overclocked from 3.6 to 4.5 ghz , 16 gig of 1866 ram , 240 gig ssd , 600 gig vrap drive for fsx & all scenery packages.

I also got my gpu changed under warranty as it was starting to fail , I had a powercolor hd 5870 , I got a msi 6970 twin frozr as a replacement , even with all this hardware my photo scenery is still going blurry , not all the time but not as good as what I have had it in the past on my amd quad core 955 be @ 3.8 ghz & the 5870 card, all traffic tabs be it airport , boats , ai aircraft are all down set low ,I tried bojotes tweak tool & it adds a real bad shimmering effect in the near distance & beyond, i also tried using some of the tweaks from it on my original cfg .

I am getting really frustrated , anyone got any suggestions to get this scenery loading up without blurries & or any FCC settings fir the gpu , thanks.

I am trying to beat the blurries too, but my computer is nowhere near your spec. Have you tried Kostas' latest tweaks instead? I have tried both Bojotes and Kostas back to back and Kostas worked better for me for this - was getting stutters on Bojotes. Basically I cant go over 300knots at low level or my hard drive cant keep up. I think.

additional to the other post, follow the Horizon manual and try the following:-

[bufferPools]

PoolSize=0

 

[GRAPHICS]

HIGHMEMFIX=1

[Main]

FIBER_FRAME_TIME_FRACTION=0.21

[Display]

MipBias=5.5 // also try a value of 6.5

TEXTURE_BANDWIDTH_MULT=216 // only for photoscenery

TextureMaxLoad=9

UPPER_FRAMERATE_LIMIT=18

I would think that flying fast at low level would require a serious amount of horsepower if you want to run at maximum detail levels. The question is......can any PC handle that? I like to fly relatively low at all times, but I also like to fly slow, so I don't have a problem with blurry photoscenery.

Ok will try those suggestions thanks , frames are locked at 30 at the moment, water was mid level , so I will see what I get , I have tried turning some scenery sliders down a notch or two but it made no difference to blurries, it just reduced the visual quality.

I will have a look at kostas tweek guide , thanks . I have read about using high anti aliasing & anisotropic settings to reduce shimmering , my ccc doesn't have a mip mapping adjuster , so I can't adjust that. The higher settings , not maxed out but one notch down improve the image quality but I know mip mapping when set in the cfg creates an awfull shimmering .

You should be able to adjust your mip map settings from within the sim. Anti-aliasing will help in smoothing jagged edges. The shimmering will almost certainly go if you adjust your anisotropic setting to 2 or more.

Settings I have been using in ccc , override app settings ,Anti aliasing 8x ,morphological filtering un ticked, filter standard, anisotropic filtering 16x , tessellation 2x , catalyst a.i high quality , wait for vertical refresh off unless app specifies , anti aliasing mode super sample aa , open gl triple buffering un ticked . How do I adjust mip mapping in sim please.

I rarely see GPU usage over 30% either. Now Vram usage can get up in the 1GB range for me though if I set the insane AA settings like some here like to use.

 

As for Photoreal, it works best at 350 knots or less in my experience and that's with it installed to my SSD and my CPU running 5Ghz...It's just the nature of the beast I think. And if you tweak it to run smoother then you're likely hurting the performance elsewhere. I like a "universal" setup though, I don't disable or change anything for any flight so I go for the best performance all around instead of focusing on this thing or that...It helped my sanity and I don't spend any time tweaking anymore. Get a lot more flying done that way.

I never had this level of blurries on my amd phenom quad 955 be @ 3.8 ghz & the hd 5870 , I don't get it, this new pc is vastly superior.

sleightflight,

 

you could try the simforums, there is a specialist nick needham for fsx and ask again.

also is ATI card not the right card for fsx you are better off with a nvidia card in case you use fsx only.

many of your tweaks will be more specified within that forum

you could give it a try

In the [TERRAIN] section of your fsx.cfg set

 

LOD_RADIUS=9.000000

 

Dave.

 

That's extremely high and might cause out-of-memory errors. A value of 6.500000 is better.

At 7.5 one of the first cfg tweaks I do , along with affinity mask 14 & texture max load 4096 for Rex.

 

Was going to get a nvidia 670 if my 5870 wasn't sorted but as I got a 6970 for free I went with it , & I've seen some YouTube vids of fsx & a 6970 & they looked really good.

Sleightflight has a higher spec computer than I (although my i5 2500k is running at 4.8), but I run with nearly everything maxed out and can happily run Horizon and other photo sceneries all day long with a Lod Radius of 9.00000 without OOM issues.

 

Screenshot taken in flight at over 300kts without pausing sim:

 

 

 

I can FORCE an OOM by flying with max settings over UK2000 London City Extreme, with VFR London and UK2000 Heathrow Extreme in view (usually whilst hosting a Multiplayer session for 6 or 8 people), but this is the only circumstance in which it happens.

 

Certainly 300kts is a big ask, but then in real life only the military are allowed to exceed 250kts below 10,000 feet. Also, I'm not sure that an ATI card is capable of the same results as NVidia.

@dave belsey: It's true that you've got a very high-end system, but the OPs system has a lower core clock and an AMD card which is going to perform worse. So I guess that such high a LOD is too much for him.

 

@FreeBird(Josh): FSX is different than FS9, so such a high TEXTURE_BANDWIDTH_MULT value is going to cause problems according to most FSX tuning guides.

You're a lucky guy then, Dave. I have to stick to LOD 4.5 in DX9 mode, although I suspect that I could go much higher in DX10 mode. I don't think FSX really likes my graphics drivers when running in DX9 mode...

I don't see your specs on here, but I'm surprised at that.

 

I run the same settings on my secondary machine, which only has an i7 920 running at 4.0GHz, 6GB of RAM. and a GTX460 with 1024MB.

Your secondary machine is still considered a high-end system today. Though I guess Chris has an AMD cards because "FSX doesn't like his drivers". The AMD drivers don't support FSX's older rendering engine, which is why NVIDIA cards get better performance.

Nope, I use an Nvidia graphics card. This is my PC spec....

 

Gigabyte Z68A-D3 motherboard

Intel Core i5 2500k CPU @ 4.3Ghz

Thermaltake Frio CPU Cooler

700W Xigmatek NRP-PC702 PSU

8GB Corsair DDR3-1600 RAM

1GB GeForce GTX 560Ti

SB X-Fi Xtreme Music

Windows 7 64bit

 

I think that I have the Forceware 196.19 drivers installed. My statement that I have to stick to LOD 4.5 isn't strictly true. I have increased it to 6.5 in the past, but I reduced it again because of my OOM errors. However, this may not make any difference at all.

 

By the way, Dave......this is the Chris from the UK2000 beta team :smile:
