The next odd, in flight, thing I discovered was that if I applied the 21 lock on framerates, whilst on EGNS finals, the fps dropped. If I removed the lock they didn't rise. I saved the situation, on finals, with fps now unlocked, and re loaded. Still no increase in fps. I shut down and rebooted the PC, then loaded the saved finals situation; fps still low. Fed up with this I decided to fly to our end of the Island. Over the sea framerates always rise. When I recrossed the coast they stayed high, so I tried 08 ILS again and they stayed high!.

So, it looks as though the higher rates from unlocking only appear if you can "clear the indigestion" by moving through a low load area, first.

Once back in the North and I landed at Andreas. I'd begun to despair of Andreas. Nice scenery and I'd changed its trees from objects to Autogen but still got single figure framerates. Not so this time. I passed overhead our house, where houses and golf course couldn't have been sharper. Landing at Andreas, I haven't seen a value below 25 fps!

It looks as though the conventional wisdom about needing to have locked fps, to leave room for other areas of FSX, may not hold good when running a quad core. Pro tem that's the way I'm going. Scenery clear and flying really smooth.

Hi Denis,

Do you have the Scotflight FSX? If not how about recent Tony Meredith freeware airfields?

Hi Gerry,

I have the exact set-up as Tom with the Q6600 and the GeForce 8800 GTX but with SP2. I have no idea what the difference in frame rates is between SP1 & SP2 but if you would like to suggest a location where we could compare, I'd like to help.

My swap from dual core E6700 to quad core Q6700 has been a bit of a let down. It was made after reading a seemingly logical and authoritative review of factors affecting FSX performance, on the Horizon Forum. That concluded that the most effective upgrade was to go for the highest number of cores available.

My first impression is that performance has gone downhill slightly. That's unexpected, since the Q6700 is said to be two E6700 in the one unit.

When I boot up the PC I get an error message that says there has been a uCode failure so press F1 to continue. It then boots up OK and either Task Master or Asus' AISuite both show 4 cores working. A Google search shows this is a common error message with the Asus mobo, which has no inbuilt reference to the Q cores, and has no bearing on performance. The cure is to Flash the BIOS. I haven't yet done that, not having any past form as a flasher!

Raising my experience on the Forum produced a reply to the effect that to get benefits from the Quad upgrade it's necessary to upgrade to FSX SP2, which I haven't done. Tom is also on SP1 and has a Q6600, with framerates about the same as mine.

I'm still running XP Home and using the 8800GTX graphics card, with 760 (?) memory.

Has anyone with a similar setup to ours moved to SP2 and found a big improvement?
