GPU Bottleneck: It is accepted knowledge that FSX is CPU and Memory intensive…Right ?? Below are some interteresting facts of the performance of my feeble attempts to get FSX running decently on my poor ole out-of-date machine. Running Win 7 with a Intel Core 2 duo 3.0Ghz Processor, Asus P5K MOBO ,no clocking, just out-of the-box 8GB DDR2 PC-6400 800HZ RAM, 300 GB WD Raptor HHD 10,000 RPM ATI Radeon HD 4980 GT, 1 gb memory video card. Flying FSX on auto pilot @3000 ft default DC3, KSEA CPU Usage 27 – 36%, Disk usage Minimum, Memory Committed 627KB Working 574KB, out of available 6264KB GPU Load 97-99%, Temp 74*c, Fan 81%, DISPO Temp 74.5*c Memio temp 84.5*c, Shader temp 81*c, Clock spd 925Mhz ,memory spd 950Mhz Approximately same results for separate runs of 10 min each. The CPU and main memory is just loafing along not dong much. I am inclined to believe that the system is GPU bound and is not sharing the load with main memory at all. Is there anything that can be done to improve this situation short of getting a high-end graphics card

Flameinghouse Many thanks for the very useful link. This paper is the most compressive discourse on FSX that I have ever seen. I had always thought that some knowledgeable person should write a book on How-To for FSX. I have not yet digested it all but it is a work in progress. Should be required reading for anyone who is struggling with FSX Thank again

Fire in the belly, Along with Bud I offer my thanks as one who is a raw beginner with FSX. The guy certainly seems to know things worth knowing. I am not doing any tweaking yet but have filed the info, thanks.
Ed

Another bit mentioned in the article ( in case you guys were reading too fast!) was to not pay attention to the CPU meter as it doesn't measure correctly. So Bud, your computer may be working harder than it cares to admit. I've tried metering while flying for a different reason, but it never seemed to be working up a sweat running FSX....

Thanks guys As I said in the above post this Radeon 4890 is just too long to fit into the PCIEX 1 slot so it has to live in the PCIEX 2 slot. My big concern is that FSX is not utilizing the CPU and /or the main memory at all. I have 8 GB RAM and I find that FSX is using at the most ,comit 649MB , working 546 MB and the CPU load is never over 37% as the CPU temperature runs at 38*c I am desperately looking for a way to force the use of all this memory. I have always been told that FSX is a CPU and main memory hog but that is sure not what I am seeing. Any and all suggestions will be gratefully welcome.

Hey, Bud. I don't know how you are getting along with FSX these days, but the other day I was making an approach to Nome in FSX - flying the Alaska Freight challenge - and all of a sudden I started getting "turbulence" that caused my R4D-6 to roll hard left, then hard right, then hard left, etc. I couldn't react fast enough to stop it and crashed. I was so busy on the yoke that I didn't pay attention to other things like air speed and descent rate. It would have been nice to have a co-pilot to pull the gear, flaps, hit the throttle and tell me to abort. This was NOT a thermal, or a down draft. I don't know what could have made the plane roll like that.. Anyway, I thought I'd pass it along since you had turbulence on your approach to KSEA a while back and I didn't want you to think you were the only one..

Does anyone have ADE or an AFCAD editor?
I need a modification to KDTW Gate Small D80
I would like the radius set to 9 meters and the airline code set to BGA
That way ATC will hopefully direct my Beech 1900D to that gate.
Thanks

Bill I have recently installed both. I have used AFCAD to put the lights and things on my FSEconomy home base 55J here in Florida, as per Skyvector. I am assuming you are working in FS9. Worked like advertised. Have not done much of anyting with ADE but hope to get to it soon. It looks good tho. Let me know how it goes for you. Bud

Does this look like what you want Bill? If so pm me your e-mail and I'll send it to you to try....FSX right? Happy Trails
