Ben Supnik said:I am still trying to dig out my in-box this morning, but Chris tells me that
there is a lot of concern over X-Plane 10′s framerate. For now I can only offer
one bit of advice:
Don’t panic.
I have no doubt that many users are seeing terrible fps with version 10. But I
think that we’re going to get this sorted out over the next few weeks and the
end result will be really good.
How can I think that when so many users are seeing poor performance? Here’s why…
* With X-Plane 9, four years after its debut, you /still/ can’t run X-Plane 9
at extreme objects on a modern computer.
* With X-Plane 10, all of 1 day old, with very little performance ,i can run
at extreme objects on my core i5 and get > 20 fps in the demo area.
In other words, the hardware usage of v9 was never properly “fit” to the
capabilities of a modern desktop. By comparison, version 10 is at least on the
right curve, and we know how to tune for performance.
Please bear with me for a few days: the current state of chaos in our server
download farm is a high priority right now, as are a few serious bugs. So if
you send me a list of your hardware specs, settings, and some numbers, I
/cannot/ help you.
When I do have time to look at performance (hopefully real soon) here’s how we
will do it:
* I will post some standard fps-test command lines that you and other users
can try.
* You can send me back the log.
One I have that data, /controlled/ for all rendering settings, across a variety
of hardware, then we’ll be able to understand performance and fix engine bugs
and provide work-arounds.
X-Plane 10 is only fast if it hits the fast path through the driver every time
it needs to; there are all sorts of little things that can go wrong that can
kill fps that are not an indication that long-term the sim will suck. We have
worked through nasty performance issues before and we will again! It took two
months to kill off the very last driver problem in X-Plane 9.0 – I certainly
hope it won’t take that long to get the vast majority of users running well in
version 10. But I do believe that fps problems we see now may be as much a case
of driver vs. engine quirks than a fundamental performance gap.
Ben Supnik said:For those who cannot wait to try to get X-Plane 10 to run fast, a few tips on
how to ‘break down’ where a bottleneck might be:
* Run with clouds vs. clear skies. The clouds chew fill rate. Are clouds the
issue?
* Turn down visibility – X-Plane 10 will run at 100 nm but some machines will
die with this. Does a low visibility help?
* Turn off the AI planes. Any better? They take draw time when on screen and
cores.
* Turn down texture res if you haven’t already. (Well, most people try that
by default.) Start with low settings and work your way up.
* Try areas away from KSEA. Compare down-town to rural, and different airports.
* If you have an nvidia card before the 400 series, try running with
–no_instancing from the command-line. This can particularly help Mac users.
In most cases there is only /one /setting killing your framerate – find it, fix
it, and things get a lot better…fix it and you’ll find those other settings you
turned down can go up at least a bit.
The gotchas in v10 are definitely different from v9. Shadows can kill your fps
in a huge way – I’ll be spending a bunch of time tuning them to look better and
kill fps less. Turn water reflections down if you don’t need them – the
“advanced” setting is frankly a bit pointless. Turn off full screen
anti-aliasing if you are going to run in HDR mode, then restart the sim.

Ricardo Rementería Troncoso said:Since version 10.04 beta 3, I only use XP10.
Thanks for offer, should we try when i have more time. I know about xpl10, but i'm curios how it work's with skypeRicardo Rementería Troncoso said:If you want to see what it's possible and what not, you can fly with me (as a passenger) using Skype and the option Screen Sharing. It works fine (XP10 and Skype). 8)
We (users of Apple's computers) normally do not change the configuration of the original computer, thus it's NOT overclocked.If your's CPU is not overclocked - i think my CPU should be work fine too, dual core at 2.53 GHz.
SURE. I've tried older beta's. My conclusion was always the same: unusable. The only version "usable" was 10.04 beta 3 (until now).Did you get improved performance after updates?
