Dave - I've been between 12, 14 and 15, and to be honest - I can't tell any difference on to the other.. for me this is one that changes with my shirt.... :lol:I will say this, though - I changed something in the last two weeks - don't know what, and I can only think of the dual limiter and stripping the scenery loads that have changed, but she will hold 40-odd AI + 40 odd-GA + road + sailboats + three layers of 8/8 cumulus from 400' right up to 7500', using gthe BN Islander or one of the singles, and she will be solid 26fps everywhere. By everywhere I mean Seattle - Renton - all OrbX. The only place that will pull it down is Vancouver+, with Nigel Grant's CYVR(5).

No-one gets 55 fps unless everything is turned way down - or they're measuring over a desert - or they're bluffing.

I get 55 fps easily when flying VFR, and I have everything full right and 60% traffic with lots of add-ons. My system is new and I can support it from a hardware perspective. Video resolution plays a role as well, so if you're using multiple widescreen monitors and he's using a 1280x1024 monitor from years ago, that will make a big difference. Please don't make blanket statements that are incorrect. The reason for setting the FSX frame limit to unlimited is because it affects the texture loading and can impact blurries and autogen. Setting the external frame limiter is to avoid tearing that will occur because the monitor is fixed at a refresh rate that is a multiple of 60Hz. If you keep your fps externally limited to 30, then you will not produce tearing.

If you keep your fps externally limited to 30, then you will not produce tearing.

Not so sure about that... The only sure way to avoid tearing is Vsynch=On, as best I know.

Same here, Bert. More speculation and rubbish.

BertI agree with you re:Vsync. One thing we all forget if you set vsync on either in nVidia Inspector or via the fsx.cfg tweak you have now limited the frame rate to the refresh rate of the monitor which for most LCD/LED's is 60 Hz = 60 fps. With vsync set on then FSX must maintain a steady 60 fps otherwise you will experience a 50% drop in frame rates which is an inherent issue with vsync (TB helps). I don't know of any PC built today that could maintain a steady 60 fps in FSX in all situations, so is it wise to use vsync at all (even with Triple Buffering on?). I have seen suggestions that if you use vsync then any fps limit should be set to an integer of 60 fps (30, 20, 15) but I'm not sure how valid that is? If we use vsync and also an fps limiter do we run the risk of confusing the video card with conflicting instructions and hence induce the dreaded vsync stutter?I use the inbuilt FSX limiter (to avoid fluctuations) with vsync turned off - but I still get slight tearing in FSX even on a true 120Hz monitor -( but not in P3D or MSFlight)RegardsPeterH
