August 19, 201114 yr Library Administrator Hey Guys, Recently I have noticed something that I dont think I have ever noticed before. I am expierencing micro-stutters. I am solid at around 30fps with an external FPS limiter. it seems to be about every second I get a tiny stutter. It is most noticable on the grround or when looking straight down. Any ideas? Im running an Intel i7 (2.67) not overclocked.3gb ramWindows 7 Home Premium 64 bitATI Radeon HD 4800 Thanks in advance. Oh, and the only new thing I have done is to install the PMDG 737NGX Brian A.

August 19, 201114 yr Hi Brian - a few ideas to explore for you: Turn off hyperthreading and set affinity mask to 14. That worked for me and many others (leaves core 0 free for the o/s and background processes and moves FSX to the other 3 cores). Usepools=0 may also help (moves some of the work from the RAM to the faster DRAM on the videocard). Turn of vsync in your videocard software (turn back on again if you get tearing as a result). Maybe a background process (such as your antivirus). A good defrag and optimisation can help (takes a long time to optimise, but worth it). Mydefrag is a good freeware program for this and there are several payware defraggers too. Let us know what success you have with these.

August 19, 201114 yr Here are the additions you need to make to the FSX.cfg. It doesn't matter where they go, though mine are at the start because i play around with them sometimes: [JOBSCHEDULER]AffinityMask=14 [bufferPools]UsePools=0 If they don't help, you can always remove them. Let us know how it goes.

August 19, 201114 yr I have had those occasionally for the 2 years I've been on FSX. The only solution I found is switching to a default plane then back again and the stutters go away for me. Sean Green
August 20, 201114 yr Author Library Administrator Ugh, sorry to say that they didnt help, it might be an issue with the aircraft, as the default one doesnt do it, or it is very unnoticable. Brian A.

August 20, 201114 yr In that case I would say it is an issue with the power of your PC. I7-920 at stock frequencies and only 3 Gb RAM for FSX in a WIndows 7 environment coupled with the NGX might be asking too much. It is clear if you does not have the issue at all with default planes. Alex
August 20, 201114 yr Author Library Administrator Thought that might be an issue, I guess I will go get some more RAM. Brian A.
