Hiya all,I just did a flight into EGLL but the approach is to difficult because the framerate is to low. So I tried to check it out, and found out that it has to do with the sound when switching in on with Q the framerates drop to 8.3 when off in goes up to 15.0????Anyone any idea how to improve it????The sound-settings in Fs2004 are set to low.I use a Terratec 512 Digital card also installed the latest drivers.On a p4 2.8, 1024Mb mem, ATI Radeon 98000Pro.Should i change a setting in Windows or in Fs2004??????? Many thanks L.Jim

Could be an IRQ conflict. Make sure the soundcard is *not* in the slot immediately under the AGP slot as this can cause problems.
