no, I think you misheard something. In no way does EC have a 10X performance boost

There are a tremendous number of error messages in the log files. Try removing those sceneries. If that a doesn't work, remove all custom scenery and plugins, then replace 1 by 1. I am assuming there is a extreme reason you are still on Mountain Lion.

really 2x? supposition/predigest or measured? But that still does not answer 'what is decent?' It would be interesting to see a version of x-plane truly optimized for the mac instead of a cross platform design understandably tilted toward the PC to attract disaffected MSFS users. The things that would enable a mac pro to slay dragons are not done (those choices either do not exist on the PC or would perform poorly), while other choices perform well on a PC but not a mac. These are programing choices not inherent positives or negatives of either system. The current situation is that XP runs faster on an iMac than it does a mac pro. If the opposite choices were made the results would be different. It is these choices made by LR, more than video card drivers, that affect mac users on XP. however, the question remains: 'what is decent?'

What do you call decent?

first, the 45+ is an indication that it is not badly optimized for the mac even if it were at an airport with no scenery, which it is not, this would show that it's not XP/Mac that is the issue Since you thought "it would be very interesting to know how [ I ] can obtain that value": 2.93 GHz i7 16GB RAM Compressed Textures Resolution: High Trees: Overgrown Objects: Mega Tons Roads: Tons # of cars: New York World detail: Very high Airport Detail: high shadow: static HDR: off Screen Anti-Aliasing: 8x anisotropic filter: 2x clouds: 10% aircraft: 172SP weather: low viz just went to an airport with no scenery: 59 FPS

You can install on a Mac using Crossover from http://codeweavers.com

Mid 2012 MBP has a thunderbolt port. A properly executed TB drive will be about the same speed as your internal. I don't think the drive is your bottleneck. How much VRAM does your graphics card have? 51GB (big problem) or 1GB (a little better.)

Wow, harsh. Have you ever paved new ground in an field? I have, it takes time, often you start over, and start over, and start over... To paraphrase Tim Cook: It's more important to be right than to be [fast]. I've been working on a pay-ware project for almost 4 years. While a lot of that was learning, much of it was clean-slate, I can do this better, start over. So where am I stuck? The ortho landscape. Looks great from the air, but looks like I need new glasses when taxing—this is a 50+ year old, highly landscaped, family owned airport. My fear? NorCal is going to redefine XP scenery to an extent that I my have to cut my target price in half.

nevertheless, I still stop by almost everyday, just to see

That would require a google account. Being in tech, I will not go there. I know too much.

A heavily trafficked road at one end, power lines and a 3m stone embankment at the other. This privately owned, public use airport is a tight squeeze. Heavily landscaped, interesting mix of buildings. Custom static aircraft.

There has not been a single successful virus with Mac OS X ever. Trojans? Yes. Viruses? No. When I say successful. I mean viruses that have spread. People have tried, they didn't spread. (Why would someone randomly enter their Admin password?) Trojans are the user's fault, but the company protects against all known trojan issues. Every time a vulnerability crops in a third party add-on (cough, flash, cough, java) it is shut down world wide until that third party updates it. Leave Symantec off, it's a bag of hurt and protects against nothing. Yesterday I did something I do every 2-3 years, I ran ClamxAV which checks every known invader to OS X. Nothing. I do this to validate my claim: I am online 24/7. Nothing.

cross platform?

sometimes the intertubes deflate

I meant no insult. I made the OSM edit in May of 2011. It shows 3 lines. At that time I saw no designation available other than Power Line. I changed it today to minor_line and, since I do not know what the voltage is, removed the voltage listing (in 2011 the potlatch editor did not present a voltage option.) I brought this up because, unlike all of the other 333 changes, which I made to OSM around the airport, this singular power line is, in fact, suppressed in the default scenery. The other changes are all reflected in the scenery. Also, all of the other high power lines in the area are there.

Looks good. Two caveats, so far. The scenery seams to treat all OSM power lines the same: A 3 wire line shows up as a towering high tension monster--this is kind of weird when it's at the end of a runway. This could be filtered and corrected in a future update. The second is a problem for scenery developers. If the dsf for an airport contains data that corrects roads around the airport, a new version will need to be created for users who also use this mesh. I see no way around this.

Here's the shortest review ever: This is the plane I fly 99% of the time. I hand fly it, it's smooth as silk. Real world Mooney 201/Tri-Pacer pilot(I don't care for the options in XP for either of these aircraft)--at one time 500 hrs a year The TT is only $25 do it

So on the Cessna Corvalis I have the watermark (with countdown) on the lower right. Distracting, but whatever. Then there are the two X-Aviation logos spread across the ASI and HSI. My guess is these will go away with the final release, but it would be great if the next beta could move the logos to the bottom and maybe a little smaller.

I reinstalled the 1.3 update and things look correct now

I'm getting a doubled and offset map on the MFD

works, but there can be a lot of z buffer issues with complex objects.

Shadows were all the way down. Turns out it was Marginal's script for exporting Sketchup to XP. It worked fine with XP9, but with 10 the Z buffer goes wild. I had a year long project finished and waiting for XP10. I'm now having to export each object to AC3D and then to XP. It may all be for nothing, however. The reason for building this scenery is the power lines 25 ft from one end of the runway and the busy road 10 ft from, and perpendicular to the other runway--makes for an exciting approach: http://g.co/maps/aee96 I can replace the power lines, but the segment of missing road is a different matter. In an email Ben stated that the solution was to wait for a tool (not currently under development) to export draped roads from OSM to XP10. As it stands now cars disappear. I may have to resort to XP9 roads--I've put in too much work to just walk away.

Anyone else having z buffer problems where none existed in XP9?

Seeing the words Bose and Best on the same page gives me the creeps, so you can imagine how I feel to see them on the same line! Spent over 30 years in the audio industry--much of it at some pretty high levels. Never meet anyone in the industry that used a Bose product. Not one person, not one product. While they are also above your target price, you might check out LightSpeed Zulu--I've seen then for $750-$775.
