Railworks America

Hi Community,

Does anyone know a fix for this? I have a high-end PC, this is the only place I get a graphical problem, and it's in the scenario editor GUI/Map

Screenshot is an attachment.

That is caused by your nVidia driver? What version? On Windows 10?

Possible remedy could be to switch off SSAA (Super Sampling Anti Aliasing) in the Display => Advanced section of the Railworks Settings screen.

It is not the drivers that are at fault, but rather Railworks super sampling those 2D screens

In that whole thread they are saying it is the driver's fault, that anything above 350.120 is causing issues.
It isn't just the maps, I was having issues with massive flickering when I put a new driver in recently. I had to revert to 344.750 on my machine.

The software industry is always fiddling with something and causing issues and the new Nvidia drivers are causing massive complaints all over the web.

Well, given that a clever person from UKTS wrote new and correct FXAA shaders to replace the faulty Kuju ones, I wouldn't be surprised if the old Kuju SSAA shaders were likewise faulty.

Railworks is probably not on nVidia's list of preferred games that need to be tested with every release of their drivers. I believe DTG has brought the problem under nVidia's attention, so perhaps it will get fixed. Then perhaps not ....

Massive flickering is also caused by wrong buffering of screens, missed syncing of screens, etc.

I am running nVidia 350.12 on my most powerful desktop with its GTX770, having refused to install anything newer on my dedicated gaming/Railworks computer, still running Windows 7.

To tPlowman: tell us some more about your Railworks graphics settings? nVidia driver settings are all on "application controlled"? On Windows 10 Home, Windows Update will push the latest nVidia drivers onto your system, wether you want it or not.
You can backdate the driver with one from nVidia's site, but it will get updated behind your back once again. Only when you switch your internet to Metered Connection, the forced updates will stop. Stupid MS decision, like so many in Windows 10.

A good analogy to the software industry would be this.

You buy a car and then after a couple of years, you buy new tires for it...
Then a couple of years after that, when the car is 4 years old, you go to buy new tires for it but can't get them anymore. The tire manufacturers tell you "Oh... well... we don't have any tires that fit, because your car is designed wrong and you need new wheels and or a new car..." You the customer would be saying WTF!!!!

And yet the computer industry has been getting away with that kind of thinking for years. Change for the sake of change, not always real improvements.

I found a strange "fix"

If you point the camera at the sky, or somewhere else that there is no object in view before entering the 2d map, it doesn't get quite as bad.

Happens to me only in the schedule editor, not the full screen map.

I assume the small 2D screen of the scenario editor is being overlaid upon the actual 3D world rendered behind and around it, judging by your screenshot. Either the SSAA algorithm or the nVidia driver doesn't know that one portion of the screen needs to be rendered in 2D while the rest of it requires 3D with FXAA and supersampling/downscaling. Given that the super sampling process messes up the 2D screens, All shaders are in the Dev/Shaders folder, so a clever person can take a look and try to improve them.

Not just a Win 10 problem but also Win 7. Set AA to FXAA+8xMSAA will eliminate the problem this is just a work around. This also happens in the 2D map view in game by pressing the 9 key. I have the latest 355-60 Nvidia drivers.

I had to go back to 344.11 to get rid of that and to not crash while painting terrain. Definitely the nVidia problem.
