Top Tip - Anti Aliasing

Since purchasing the West Highland Line route, I noticed for the first time the so called 'rubber banding' effect on the track sleepers.

I've got a fairly poweful PC and not seen it on other routes so I was somewhat suprised and disappointed to see this. No amount of messing around with the in-game settings cured the issue. I noticed a post buried in one of the threads which suggested altering the anti-aliasing setting in your graphics card control panel and setting it to the maximum of 32.

I've got a fairly high end Nvidea card but found that in the control panel it was set to 16. After altering the setting to 32 I'm absolutely staggered to discover that not only has it cured the rubber banding issue but it's improved the overall graphics in game by an incredible degree. It almost looks photo-real in places. It's like having a new simulator and with no adverse effect on frame rates either.

In all my time with this sim (day one of Rail Simulator) I never knew about this setting and its impact so I thought it worthy of a thread so that others might be able to improve their experience also.

Are you confusing anti-aliasing with anistropic filtering there jimmy?

My anisotropic filtering can't go upto 32, so don't know if that helps answer Gary. I do however have 32 as an option for anti-aliasing.

It is the definitely AA setting but it depends on the card for example my GTX750TI Maxwell has a maximum setting of 8 but a GTX 670 has a setting of 32 x CSAA. Unfortunately in my case the 32 x setting does not entirely remove the rubber banding effect (on some routes) and fixing that seems to make the OHW flicker a little worse.
JS was this with dynamic Lighting and Dynamic skies ticked?
Is the setting in your case 32x CSAA or just plain 32?

Ahhh...I'm with it now. I'm not sure whether there actually is a 32x anistropic filtering, but as I'm using an old GPU the newer kit may support it. Basically with this AA tweak you're over-riding the games settings and using the GPUs CSAA--do you, and jimmy, just have the numerical value and not "32x CSA"? as just quoting the number threw me (that's my excuse anyway)

Tried this with my AMD and it completely broke the sky and ground textures. Train looked great and I was getting insanely high FPS mind you :)

jimmy, did you apply this as a global setting or do you have a custom profile set up for Railworks.exe?

I have 32xCSAA as my choice of setting, running a 650Ti 1Gb

Yeah, my 550 shows it as 32x CSAA; I'm sure jimmy is using a higher card than either of us so I'd be surprised if he just has a number.
Not that it matters of course, by now we all know where to look.

jimmy, out of interest, what in-game settings are you using?

Go to Control Panel, then nVidea Control Panel. Left hand pane, expand 3D Settings, and choose Manage 3D settings (you may need to change the view to Advanced, or Show All Options--I can't remember if it opens in a simplified version by default) Change Anti-aliasing mode to either Enhance or Overide and then the Antialiasing--Setting option is enabled. Click the little down arrow in that and choose the setting.

More questions jimmy,,,
What graphics card, and more importantly, what driver version are you using?
Getting the nVidea control panel settings to override the in-game settings has been rather problematical and 'hit-and-miss' for many in the past.

Yes I have had the Anti Aliasing setting turned off and had it set to game control. I have turned it to on so that the card controls the graphics and set the setting from 16 to 32 and changed a couple of other settings, and TS graphics seem a bit better. Only have tried on one route so far JTs Bristol to Exeter which I know is not very graphics intensive. Well try some other routes later.

I'm running an Nvidia 770GTX. I'm a couple of driver releases behind the latest because all is running sweet and I don't feel the need to risk an update for no reason.

I changed the settings via the Control Panel rather than the standalone Nvidia Experience interface. Simply set the option to allow the card to overrule in game settings, bumped the anti-aliasing drop down menu to 32 and boom, like a new game.
