Thanks Nick for the chance to look at the Radeon card demo.  My only problem is that it doesn't tell me much.  I can slide past scenery like that with my 8800 card every bit as smoothly and with similar definitiion.  Be it Switzerland or Canada it is the same.  The test for our business is 1500ft over Long Island, Seattle, London or Sydney using native autogen.  Bring it on.

If you will post the following information I will run some numbers for you to try in FSX


I need to know:

CPU speed in MHz and type of processor
Front Side Bus in MHz
Memory Speed and manufacture
Memory Timing (ex: 4.0-4-4-11)
Memory commad rate (1T or 2T)
Video card manufacture
Video card core speed
Video card memory speed
Video card memory amount
Motherboard model

I do not want to know the default values if you are running overclocked. I need to know what the system is running during FSX use.

Heretic

When you get situated and have run the test flights please let me know what is happening. If you are still having problems with microstutters or blurs, please elaborate specifics about when and where these probalem may occur and I may suggest some changes.

As I promised I researched your video card. The memory on that XFX card is most likely not the faster Hynix HY5 BC573225A FP-11 which was reserved for the XXX edition of the brand and as such the bandwidth on it i@ stock 64GB/s which should be the same as Black ZR1's PNY.

If you are running the XXX Edition, the memory on the card will run much faster and deliver 74GB/s at stock speed.

If you think you have it locked down fairly good but are simply having a few small problems here and there I am sure those can be trimed out fairly easy.

Nick: I am interstate away from my machine, but I shall get this detail to you within a week.  Sorry that it will take that long.  At the moment I have a little Lenovo supplied by my work that I take on trips.  The computer has less processing power than my USB mouse - but a really good Next G card: which is as good as it gets in a country (Australia) that is still fighting over the installation of the highest speed broadband.  But it does mean that I spend time on the fora and that's how I have been able to learn so much from these threads on Simviation.  However my card is a stock standard NVidia 8800GTX, and my CPU a new Pentium 6700 - again stock standard and no overclocking. I have 4 gigs of DDR2 RAM, but I will have to check on its make. So too with the motherboard, an S series if that helps, which was new with the video card.

[macca22au]

Nick: here is a little more info about my system that fills out the detail.  But it is probably insufficient for your numbers. Hope it helps, as everything is unmodified, and in the next few days I may go into the manufacturers sites to get more info.

CPU is an Intel 6700 dual core, nominally 2.66 ghz

NVIDIA 8800 GTX

Gigabyte S series motherboard

4gigs high speed RAM

Vista Home Premium

Ian, when you get back to your PC, try downloading CPU-Z. Once downloaded, extract to any folder (using Winzip or WinRAR), then run cpuz.exe.

Go the the CPU tab and read out the:
Name:
Core Speed:
Rated FSB:
Cache:

Then go to the Mainboard tab, tell us everything it sais on the Motherboard and BIOS parts.

Then go to the memory, tell us everything there...

And please tell us what brand your 8800GTX is? If you don't know I think Nick'll assume it's generic.

Houston, we have a problem


That nasty weather we had today brought out a micro stutter issue. It was 10 time worse around the city area. Today was the first really good rain and overcast real world weather day I have had to test on. I have been using building storms because real world around here has been clear.

I did install those trees and I see what you mean. They seem to work but only in certain views.

Strange.


If I drop fiber frame the stutters smooth out but you know what happens as soon as I did than

Rofl.

My computer:
Intel 925xe
Pentium 4 650 (17x200, 3.4ghz, 2mb L2 cache)
4x512mb RAM (Dual Channel at 266mhz, 4-4-4-12 I don't know Command rate)
X850XT PE (540 / 590 37.8gb/s)

can run the settings at:
TERRAIN_MAX_AUTOGEN_TREES_PER_CELL=1150
TERRAIN_MAX_AUTOGEN_BUILDINGS_PER_CELL=575
AUTOGEN_DENSITY=3
TEXTURE_BANDWIDTH_MULT=96
UPPER_FRAMERATE_LIMIT=18
PoolSize=2575000
FIBER_FRAME_TIME_FRACTION=.28

Very smooth but I still get stutters in cities. Hmmmmm, I know I can get around this, however I am not sure how. Ingame I usually have a minimum of 15mb of VRAM so I cannot boost poolsize up much.

Nick, how high do you think my TEXTURE_BANDWIDTH_MULT=96 should be at?

[ATI_7500]

I did the Chkdsk and surprise, surprise, it found and corrected errors on C: but none on D:.

Haven't tested FSX yet, but will do later.

*Bump*

FSX is up and running...and blurred.
This is not a new problem to me (been fighting them from the tests on), but I just can't seem to get rid of the ground textures blurries, no matter what kind of values I set in the .cfg. Autogen doesn't have anything to do with it. I could set numbers as low as 2000/1000 and still get them.


Numbers producing less blurries than Black ZR-1's:

TBM = 320
FFTF = 0.36
AG density = 3

Autogen still at 3000/1500...I think I'll fix this as my lower end.
