OpenRails v360 performance

[conrail1]

Here are some screen shots of OpenRails v360 performance on a i7 980X/Nvidia GTX 480 based machine. I choose the Feather River Route again as I did with v128 as it's probably one of the most demanding routes for MSTS.

It seems that despite the added eye candy/physics in OR v360 frame rate performance still remains very good.

All of the screen shots were originally taken at 1920x1200 resolution, 8x super-sampling AA/16AF on Windows 7 64-bit with the new Nvidia 260.63 drivers.

143 fps-





109 fps-






Even with a yard full of equipment/track frame rates still remain well above 60 fps -


77 fps-





98 fps-

Cool pics and glad to know the performance is still doing well for you!

Forgot that I had this route too and yes, it is looking great, FPS av.70 with my ATI HD 4870.

The US NTSC HD-TV framerates apparently being 30 FpS @ 60Hz anything above that is a smothness bonus !

30 fps on a monitor with a 60Hz refresh rate would obviously be a mis-match and wouldn't be smooth at all.

A consistent 60 fps with a monitor running at a 60Hz refresh rate is the smoothest your going to get.

As soon as I get a chance I'll be putting up some screens of the performance I'm getting with another setup I'm testing with that uses i7 with an ATI 5870 video card.

Dan,

Thanks for your meticulous testing of the Open Rails software and your excellent looking screenshots. I am glad to see that Open Rails can handle populated yards with additional rollingtock and locomotives.

Thanks Walter, it is impressive to see yard/terminal scenes that ordinarily bring MSTS to a crawl, not even seem to effect performance (or very little performance impact) when the route is running in OpenRails.

I have no frame rate problems problems with routes like the Chicago Stations which features one of the most complex track layouts in a relatively small area that I am aware of in a MSTS route, running in ORTS at 75 FpS.

There’s a simple way to compare just how demanding the route is, post some screen shots of the Feather River Route of Oroville yard full of equipment along with the other route that you think is demanding.

Make sure you mention the resolution used and AA type/AF applied as the performance isn’t going to mean much if the image quality isn’t there.

O.K., here is my last response to any of your posts.

You have a PM.

Like I said earlier to make a usable performance comparison the resolution and AA/AF have to be mentioned.

Post a screen shot of the Oroville yard at the same location as I did to get as much of the yard in the shot as you can and then show what kind of performance your getting.

How many cores are being used? How fast is your cpu running? At 4 GHZ 3 cores are used on my 920.

How many cores are being used?

Here's some info taken from page 32 of the OpenRails documentation -

http://www.openrails.org/SoftDocs.pdf

Multi-Threaded Coding


The Open Rails software is designed from the ground up to support up to 4 CPUs, either as

virtual or physical units. Instead of a single thread looping and updating all the elements of the

simulation, the software uses four threads for the main functions of the software.


Thread 1 - Main Render Loop ( RenderProcess)

Thread 2 - Physics and Animation (UpdaterProcess)

Thread 3 - Shape and Texture Loading/Unloading (LoaderProcess)

Thread 4 – Sound

How fast is your cpu running? At 4 GHZ 3 cores are used on my 920.

I used my i7 980X based machine for those screen shots which operates at 3.3 GHz. Why are only 3 cores of your quad core 920 running at 4GHz?
