4gb Patch

[djt01]

We didn't had to downgrade our expensive hardware.

Why would you have to “downgrade” your “expensive” hardware?

[bab7000]

If you do read some of the messages, you'll see, that more of us had lowered graphic details, just to minimize crashes. Don't have to now.

@Smarty. Looking forward to your next scenerio. Don't hold back on the AI's

Dose this mean that us on higher spec computers can bet better frame rates to?

Give it at try

Hi.

Well, two days of running the 4Gb Patch and i am extremely impressed.
I was happy with my system when running RailWorks but adding this has made a considerable improvement.
I am running Windows 7, nVidia GTX260, 4 Gb memory and Intel Duo 2.66Ghz cpu. I have now increased the settings in nHancer, which I could never have done before adding the patch.
There is a frame rate increase of around 10-15.
I can, also, remain in World Editor until I exit by choice and not when I was thrown out with a Proc Error.

Regards

Clive

Not really sure it applys to me as i have 8gb of memory?

[ihavenonamenoreallyidont]

Yes, it applies to you. It's about enabling the program to access more than 2gb of memory.

It does nothing to help performance (frame rate) or improve the way RailWorks loads scenery.

Hello
Yeah ! Yeah ! and Yeah !

Me too this patch 4Gb improve more on full high setting graphics features in RW...Before when I was running Peppercorn Pioneer scenario I get allways hang bug in area entrance of Newcastel (on the first 20 Mph speed limit most of the time) the entire loading scene was difficult for the hardware !

Since apllying 4 Gb Patch, for two days test on this scenario, I get allways quickly drop down FPS but NO MORE hang bug...!

Overside I don't get better FPS as before ; it seems the same amount of FPS (by me)

My spec : W7 Pro 64 - i7 965 - 6 Gb of Ram - 4870x2 ATI GC

Thank you very very much for this find

Best regards
gerard

Thanks bigphill2. I spent hours tweaking my settings to run Ghostcav's brilliant Wales & Borders and had to settle for reducing the texture quality as the only way of it not crashing Railworks to SBHH near Sugar Hill. Then along comes this little patch. I put all the settings back up to max and charged out of New Street and sailed through Sugar Hill with no problem at all. I've just completed all 3 of Pacerpilot's fantastic scenarios for W&B on full settings withou a hitch. I had a look at Task Manager and Railworks was using about 3.8gb of memory so it clearly has improved performance significantly. I am running Windows 7 64 bit with 8 Gb of memory. Rich Cooke

Sorry, but I'm going to have to play stupid one here, can somone post a direct link to the download, I cant seem to narrow it down, the only website I can find the 4gb patch just keeps timing out on me, and I'm not even convinced it is the right site either.

Rob,

This link worked for me a moment ago: http://ntcore.com/4gb_patch.php, took less than a second to connect the first time but much longer the second.

Hi

I have my computers built to order by an expert and leave it to him to set up and test them. I have not had any trouble with the 108 update or RW crashes in general so I am now thinking that my builder might have had the forethought to ensure that something like the 4gb patch was installed initially. This might explain why I am largely trouble free. I note in the system specification he has added the description 'Physical Address Extension'. Is that a patch of some sort?

It could very well be that he knows how to set up hardware and properly install an OS so that you don’t need the 2GB aware trick.

If this a 32-bit OS your running on he might have applied the /3GB/USERVA=2560 switch to the OS.

With the three systems I’m running RailWorks with update 108 on, not one of them has any issues and nor do they have the 2GB aware trick applied to the exe.

I thought I had died and gone to heaven when I first ran RW with the 108 update under WIN7-64. Great performance and no SBHH errors at all. So, I passed on the 4GB fix because I figured I didn't need it.

Then I installed Dave Brindley's Class 86 and some repaints and learned that the repaints wouldn't display properly with RW's Object Texture setting on "medium" -- they require the setting to be on "high". So I changed the setting and immediately got a SBHH crash in the very first scenario I opened in Cresston, a very asset-lite route. Like an idiot, I then tried to open Wales & Borders. Of course, boom-crash.

On a whim I decided to try the 4GB fix. After patching RW with the fix it now runs just as well with the Object Texture setting on "high" as it did when I had it set to "medium." I ran the Wales & Borders route from Cardiff to Castleford with no crashes and only minimal pauses at tile changes. While I was doing this I monitored the Performance and Processes tabs in Task Manager. Before applying the 4GB fix, Railworksproc would use max 1.7GB of RAM while running W&B with Object Texture set to "medium". Running it today with Object Texture setting on "high", Railworksproc was using 2.7GB of RAM (all real RAM, no virtual memory). This would not have been possible without the fix.

So, djt01, I disagree with your repeated statements that RW runs fine if everyone would just have systems like yours. My system is not "botched". Every other program and game I throw at it runs perfectly fine. No crashes, ever. It's RW that's botched. My conclusion is that the fix works. The RW guys should patch the program so everyone can benefit without having to use a 3rd party utility.
