I was running a test flight in FSX with the PMDG MD-11 info the default KSFO, and noted that as I was approaching the airfield the response time for Radar Contact got slower and slower...the frame rate also decayed, until the sim froze with 9 fps showing on the frame counter.I re-ran it, with traffic turned down from 60% to 35%, and there was no lockup, but the response times got pretty slow again. Tried again at 60% with GA traffic turned way down, and it cleared me to land while I was about halfway down the rwy on landing rollout.I was also running ASA (wx was scattered clouds) via SimConnect from a remote PC.Anyone else seen this sort of slowdown? It seems related to UT II--the TCAS was a mass cluster of traffic icons. Is the new traffic program capable of pushing traffic levels high enough to bury either RC or perhaps even FSUIPC?RegardsBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO

FSX is known to require high performance. Add your supplementary programs and you have quite a load. Be sure you have the latest FSX patches that contain performance enhancements to some degree.RC by itself does not generate much of a load (make sure debug is off) except for a momentary burst when assembling long comm phrases such as clearance and ATIS. FSUIPC is a very efficient performer.As you know, AI aircraft can in great numbers require greater CPU power as their numbers increase. You've already noted that in your description.ASA might command more CPU intensity than earlier versions. There have been a few service packs addressing memory leaks and other issues. This could cause HD paging (excessive memory temporary storage using the HD) as available physical RAM gets reduced. While it is on a separate PC it might be making more demands requiring more CPU power on your host due to increased net traffic if something is awry on your ASA PC.You don't mention your hardware setup. For best performance you should have an independent video and sound card so ram is not shared. In XP 2 GB and in VISTA 3 GB would be minimum. Make sure your HD is internal or external SATA, not network or USB. FSX with the latest patches does not take that much but better advantage of a dual core processor so the fastest clock speed is desired from what I've read.3D rendering in FS is mostly a CPU function, hence the slowdown as more objects with more complexity enter your image.By UT if you are referring to the terrain enhancement Ultimatte Terrain that does increase rendering requirements as well from the resulting more complex terrain models. If you can disconnect from the Internet by after downloading your weather once. Stop any unneeded security processes to improve performance.You can bring up the Task Manager performance tab to run in the background. Set it up to monitor disk swapping, ram usage, and CPU performance. As things slow down quickly pause the sim and alt-tab to the task manager performance screen to see how your cpu and ram availability are functioning. Grinding to a virtual halt sounds mostly like memory starvation.I suggest looking at the hardware forum here on AVSIM and also forums and articles on tomshardware.com. Their latest benchmarks include FSX now. Those are the places where the best help might be available.

was pre-recorded chatter playing? if so, turn it offjd

Was ASA set to global mode? Because there are several issues with global depiction on (I have the same problem too), but if you disable it (assuming it is enabled) you should have no more problems. It happens on both FS-PC and remote ASA installations. I am talking about RC slowdown only, of course. The cause of FPS drop is usually caused by AI.Fede

If ASA has this feature turn off ASA Skywatch on I think 122.0 so it doesn't load down audio performance.See this forum for ASA updates, the top pinned topic:http://forums1.avsim.net/index.php?showforum=171or register on their new forum:http://www2.hifisim.com/

It's not that one Ron, believe me. I tried everything, every single setting on and off, switching from core to core, adjusting the cpu priority... The only option is to disable global depiction in such cases. Rc starts working normal again.Fede
