I stopped using Microsoft operating systems years ago, but I didn't think there's still such a huge difference for the performance.

From my experience, the difference in V.10 is much more noticeable than it was in V.9.

Did you use the same settings in your Nvidia driver ? Are GNU/Linux OpenGL drivers better than Windows OpenGL drivers ?

I didn't touch the driver settings. I just had Ubuntu grab what it said was the most current NVidia driver it had access to on its software server. Perhaps choosing drivers in a more intelligent manner will give better performance?Which alternatives are there to choose from, how do I get them and which are you using?Also, would you give us more detailed information on your settings and your system specs?Thanks

Hi J.P.Wish I could say my experience was the same.About a month I installed Ubuntu 11.1 64bit as dual boot with the system in my signature and didn't experience anything close to what you see. Performance was no different at all, no more no less.I did however have issues with certain things like the hat switch on my Saitek yoke (there is a workaround), and my home cockpit board bu0836x. The Anti-Aliasing was also messed up. It wouldn't work unless HDR was on, then the frames tanked. I tried with the generic drivers and the ones direct from AMD.As you can see in my signature I'm using a higher end ATI card, it could be the same issues affecting it in Linux as well as Windows. Although, I'm pretty sure XPX's issue with ATI cards is Laminars, and Laminars alone, as I don't have any other issues with Opengl titles, only XPX. It's a shame, because I like messing around with Ubuntu, but as this machine is for "gaming" only, and there was absolutely no advantage to using Linux (actually drawbacks) with XPX on my machine, it no longer has a home on my computer. About once a year I give the current release of Ubuntu a try, and always end up un-installing it. They are just not ready for high end gaming yet, neither is Mac (besides, they are way too expensive for a gaming rig for what you get, 1gb video cards just don't cut it today, and they start at $2500 Canadian,that gets you a ATI 5770, don't think so), leave that to Windows. People may hate Microsoft, it's the only viable option outside of consoles for a descent gaming system. It's commendable that Laminar / Austin tries to reach out to the masses, but I have to wonder what XPX would be like if it were "Windows" only, and they didn't have to spend what must be an unmeasurable amount of time trying to please all three operating environments.Just another observation from a long time Linux user, so others don't get too excited, and then end up disappointed.GlenEdit: I will say though, that XP9 runs full out on my system at 60fps, so they got that version right in the end. I'm sure they will get XPX sorted out across all three platforms. We as end users sometimes get frustrated when it takes so long to get things right in the Xplane world, forgetting that they have to get it right three times, just not one.

Interesting! From reading around the Linux forums I did get the impression that there is a general consensus amongst the Linux crowd to stay away from ATI cards. My understanding is that, while ATI cards are catching up, they still have a lot to improve on as some problems continue to persist. I can't personally comment on it, but the issue does seem to pop up into discussion rather often.

Yes, it is a pain in the butt. I run a 3 monitor Eyefinity system. If Nvidia had a reasonable / viable option to run 3 monitors, I would buy the card faster than I could get my wallet out of my pocket, unfortunately they don't. When Nvidia offers a single card, 3 monitor solution, I will be the first to buy it. Forcing people to use 2 cards for 3 monitors is ridiculous these days.Glen

Ok, i'm ready to try Linux, can somebody post here how to install xpl 10 in ubuntu 11.10 - 64bits, or link to some tutorials?I googled it, but there is tutorials only for xpl 9

Here you go:http://www.x-plane.com/downloads/dvd-installation/

You can install X-Plane 10 like X-Plane 9:http://forums.x-plan...showtopic=49106I'm using Ubuntu 10.04 64-bit (LTS) with the latest drivers from the Ubuntu-X-Swat PPA. Core 2 system with 4 Gb RAM, 8800GT GPU with 512 Mb VRAM, stable 60 FPS with "overlay" shadows, with HDR off, with add-on plane and sceneries at 150 knots. See last picture for the framerate: Looks like X-Plane 10.04r1 has been made for Ubuntu 10.04. B)Happy flying !

That is the reason for all your problems.I have been using Linux exclusively for 8 years now for everything (except - unfortuanately FSX flying).Everybody using Linux knows that to do any serious work you should steer clear of any ATi cards, and stick to nVidia ones. ATi never properly supported their cards under Linux.

I had the same problem in my 6-core, Radeon 6770 4GB Ubuntu 11.10 box, although HDR always was better than X-Plane on Win7. Switched to Gnome Classic without effects (no Compiz) and AA started working. Now I get twice the fps in Linux, so happy that I'm actually considering not booting Win7 again (wouldn't be able to play MW3 though...) :)

I installed Linux Ubuntu and can't get my mouse and keyboard recognized. What's odd is they they worked fine when I was booting off a usb. Weird...I feel like I have a long hill to climb here, new OS, new FS.The forums have workarounds but it's like they are speaking a foreign language, I have no idea what they are suggesting for me to do.

Guys, I am more than willing to reinstall Ubuntu and give it another go, have nothing better to do. I did use Gnome classic, no Compiz, it made no difference.There is however one thing that will always keep me from dual booting Win 7 and Linux again on a gaming rig, and it's the fact that AMD do not support Eyefinity with the Radeon series of cards, which pretty much limits them all, and no, Nvidia are not an option, for reasons stated below. The only AMD cards that are supported, are the ATI FirePro cards. To get something similar in a FirePro spec wise to what I have now, is going to cost twice as much money, not worth it just to run Linux. As I stated earlier, it didn't look as good, probably because the AA wasn't working properly. And, as I said in another post here, if all you want to do is run a "vanilla" system, with no home cockpit stuff, or multi monitors, perhaps Linux works fine, but those are limitations I'm not willing to accept or put up with. Things work, or they don't, and for more advanced flight systems like mine, XPX just doesn't work properly in Linux, but it works fine in Windows, and gives me the same performance numbers.Right from AMD, and what I found when running Ubuntu 11.1 64bit with my ATI 6970.

1. 1. ATI Eyefinity technology can support up to 6 displays using a single enabled ATI Radeon™ graphics card with Windows Vista or Windows 7 operating systems - the number of displays may vary by board design and you should confirm exact specifications with the applicable manufacturer before purchase. ATI Eyefinity technology works with games that support non-standard aspect ratios, which is required for panning across multiple displays. To enable more than two displays, additional panels with native DisplayPort™ connectors, and/or certified DisplayPort™ adapters to convert your monitor’s native input to your cards DisplayPort™ or Mini-DisplayPort™ connector(s), are required.
2. ATI Eyefinity technology can support multiple displays using a single enabled ATI FirePro™ professional graphics card; the number of supported displays varies by card model. Microsoft® Windows® 7, Windows Vista®, or Linux® is required in order to support more than 2 displays. Depending on the card model, native DisplayPort™ connectors and/or certified DisplayPort™ active or passive adapters to convert your monitor's native input to your card's DisplayPort™ or Mini-DisplayPort™ connector(s) may be required. See www.amd.com/firepro for details.

Laminar need to sort out their problems with AMD cards in XPX (more so the 7000 series), and it is their problem. The cards work just fine everywhere else, even in OpenGl environments, so it is a Laminar problem, contrary to what some may say, or have you believe over at the org. And AMD need to fully support the Radeon line of cards in Linux, with regards to Eyefinity. Just to add another, Nvidia need to manufacture a graphic card that supports triple monitor set-ups like AMD does with Eyefinity, having to buy two cards just to run three monitors is a joke. Until such time, Linux is not an option for setups like mine, as a "gaming system", that point needs to be stressed. If your not gaming, it's great.I do run a triple monitor setup and will never go back to one, I don't care how large the monitor is, its not the same peripheral view when the monitor is flat to your field of view, those side monitors need to be angled to get the "real world" effect. Now if someone made a 45" wide monitor (that's what I have with 3 monitors) that was curved in the outer thirds, I / we would be in business. You could have bought one back in 2009, a Ostendo 43" curved monitor, it was going for $8000 at the time.Anyways, to summarize. Even when I had Ubuntu on my system and was testing against Windows 7, there was no difference in performance, neither one was any better than the other. So, I suppose if all you want to do is run a bare system with no added hardware functionality, Linux is fine, other than that I wouldn't bother, the benefits are just not there. You also have the drawback of not being able to run a multitude of other Windows only software. I did try Linux only for a while, and tried to get Windows stuff to run in "Wine", or "VMWare", and they ran, but not as well as they did natively in Windows. So for all these reasons, Linux is not a viable option for me, fine if you run a basic setup, my opinion of course.Glen

I personally saw no difference in XP10 performance between Kubuntu Linux and Windows 7 on the same machine. I copied my install directory from Linux to my Windows partition, settings and all, so it was a true apples to apples comparison, and framerates were identical.

Yep same, here. No difference in Linux vs Win 7. I liked the linux OS, but there was a little too much do-it-yourself for me.Also I am not sure that SLI was working.

There is however one thing that will always keep me from dual booting Win 7 and Linux again on a gaming rig, and it's the fact that AMD do not support Eyefinity with the Radeon series of cards, which pretty much limits them all, and no, Nvidia are not an option, for reasons stated below.

Ati Eyefinity, GNU/Linux, 63 Megapixel:http://www.youtube.com/watch?v=N6Vf8R_gOec

Doesn't work with a 6970 in Ubuntu 11.1 64bit with XPX, and as the posted information from AMD states it's not supported. So, something has changed with the 6 series of cards, Ubuntu, or XPX. I did see that video when I was searching for a fix a few months ago, my search led to a bunch of dead ends. Nice that it worked 2.5 years ago though, doesn't do much good now.GlenEdit: Ok, I just spent close to an hour (why I don't know) searching the Ubuntu forums and around the net in general, and still couldn't / can't find anyone who has had success getting Eyefinity working properly in the latter releases of Linux / Ubuntu, and definitely not with a 6 or 7 series AMD video card. Some people were getting it to work a few years back with the 5 series cards but still had issues. The only "fix" guys are offering to people with 6 series cards is to try a driver from the 5 series, nice.XPX would show up on my three monitors in Ubuntu, but the scaling was way out, AA didn't work right, XPX didn't recognize the odd resolution, and the screen tearing was worse than what it is in Windows. Eyefinity without Bezel Compensation should be 3840x1024 with the monitors I have, and Ubuntu was not capable of doing that resolution because Eyefinity doesn't work, and neither does Bezel Compensation which is also a pain not to have.
