Windows 8.1

[Ianrivaldosmith 5,317]

Hi all, in Windows 7, in a scenario I have saved, my FPS were pegged at 30FPS, and cpu load was 0.997.

 

In EXACTLY the same scenario with windows 8.1 and EXACTLY the same x-plane settings, the FPS are 19 and CPU load is only 0.79?

 

What's up with this?

 

Is 8.1 slower than 7?

I read something the other day equating GPU performance to CPU usage.  I think 8.1 has features to relieve some of the workload on the CPU.    I had seemed to notice, before reading this, that the more "stuff" I threw at my system when running x-plane, the better it performed.  You might try loading more CPU intensive things at it and see it your FRs improve.

Edit:  I just noticed your other post and it seems you have already tried. Oh well, I tried!

[Ianrivaldosmith 5,317]

Yeah mate I tried. It's the weirdest thing ever. It's since going from windows 7 to 8.1.

 

Performance has tanked!

Yeah, I run it on a Windows 7 machine with throttle quadrant, yoke, pedals, and TrackIR 5.  I have another copy that I run on a Windows 8 machine with a X52 Pro  joystick for several planes with more than 4 engines and helicopters.  Windows 8 is a strange animal.  About time I begin to think I am figuring it out, something else pops up!  I don't think 8.1 is particularly friendly with X-Plane and many other programs.  If they're going to design an OS for a tablet, that should be it.  Give us Windows 7 or equivalent for desktop/laptops.

I'm tearing my hair out here with this! Can't understand it at all, even using the same video driver!

Could it be caused by just dragging the x-plane folder over on to the new OS?

First thing with XP troubles is to always REMOVE xp/output/PREFERENCES.-

 

I've 8.1 as well, but I prefer to run all my Win apps on Ubuntu with Wine...

It sounds like the video drivers are not yet optimized for the new OS. I doubt that it's related to I/O operations since you're CPU usage is fairly low. I think other graphics intensive software has performance issues with 8.1 so you probably aren't alone in this.

Currently I'm a happy Win7 user. If I should update my hardware and Win7 is not an option, I will go back to Ubuntu.

I've tried 3 sets of drivers now, all same results. Looks like I can't use x-plane 10. Damn. I can't go back to 7 due to other stuff on the PC.

Tried that, did not work :(

XP10 running great on Windows 8.1 for me.

Nothing special but running a GTX780 with latest drivers.

 

Sorry that's not very helpful to you but just so you know it's not necessarily W8.1 that is broken.

[Ianrivaldosmith 5,317]

I've gone back to windows 7, and it's now working perfect again. So I have no idea what was causing it in windows 8.1

 

Same rendering settings, same display driver, same plugins. Same everything just different OS!

 

Windows 8.1= cpu load of 0.70 and slow performance.

Windows 7= 0.97-0.98 cpu load and smooth 30-60fps performance!

Zero problems with FSX or P3D v1 and v2 with Win 8.1.  And that's using an ASUS Q550 LF Laptop with an i7-4500U and GeForce 745 M.  Of course P3D (both versions) run much better than FSX.  To many people are quick to blame Win 8 for their problems when perhaps it's their machine.  I've used Win 8 since it was in Beta and FSX and then P3D ran fine.

He is talking about XPX not P3D. Speaking of PD3 i get a lot better performance out of XPX then PD3 V2 with similar rendering settings.

My bad.  Sorry.  Failed to notice XP

I still use Photoshop 7 etc. I've tested newer versions but they slowed me down to about Gimp level. (where the heck is that etc.)

I could not care less about Windows 8.1, I got sick of. Anyone still using Win7, stick to that.
