its obviously because otto thought 18 was 16

Correct, 16 is was I read it at !

But below shows that even at conrail1's time of 15:11 it shows the long shadow of the palm tree on the left but mine does not at 16:17, all shadows being shorter, assuming that the season in his screenshot is also in Summer.

Anyway, the shadows are there, one of which I could not see, it being short and can now remove this issue from my mind and get on with reporting something more useful for the team !

Not sure why i have all these jaggies at the top of the train shadow though.

The shadows are a single image stretched over the terrain (kind of); as the sun sets, it gets harder to keep a good level of detail as it gets stretched out more (like the shadows themselves). Here you can see the pixels of that shadow image as the "sawtooth" edge of the train shadow.

So is that a problem with my hardware James, or will it occur on all setups ?

No Train Brakes

In our Bernina trainset I found that all trainsets I tested brake correctly, with the exclusion of the ABe 4/4 I (downloadable here http://rhbformsts.spoorpunt.nl/ABe44I.php?m=1 ), where only brake release and emergency brake work, while brake apply doesn't work. But I must say that I am not an expert in braking parameters, and perhaps I put an incorrect set of parameters in the .eng files.

I forgot about you reporting this, having since found that the train brakes on all default and other add-on locos I have tested so far also do not work, the SD40-2 having problems of it's own !

The RhB_Bexp2 and RhB_ABe44III train brakes also do not work.

The front axles of the Aussichtswagen are counter-rotating.

Could you test the train brakes of a few MSTS default and other add-on locos ?

O t t o

P.S.: Apologies to my dear departed friend Cyndi who supplied the cab modifications for this MLT Dash-9 which has since been downloaded from my web site by thousands, being part of my MSTSBin mp3k-cons.zip, making it a MLT Dash-9 Cyndi-Otto one.

Observe the MSTS F5 HUD, it's display order we could do with in ORTS !

It's the way shadows (currently) work, so will happen for everyone. We're always looking at ways to improve such things, but as I alluded to earlier there's lots of trade-offs to be made and certain cases will look worse than others.

James,

thanks for the info mate. My system is over 3 yrs old, but i am running 2x Geforce 8800GTX @ 768mb in SLI mode.

So total video mem is 1536mb. But i guess my Intel Core 2 cpu @ 2.7ghz x2 is a bottleneck, as is the 6gb of DDR2 sys mem.

Which i understand is not blazingly fast compared to DDR3.

cheers,
Mike.

What in the name of San Juan Hill, is that green object stretching skywards.

Also another thing i have noticed on a couple of routes, missing bridges.

That's the beanstalk... you know, from Jack and the Bean Stalk. Big giant at the top.

I hope he's wearing breathing apparatus then Dave.

From my testing with v128 (I highly doubt v360 is any different) multi-GPU's (SLI and Cross Fire) do nothing to help the performance of OpenRails at this time.

You can do a comparison with both cards in SLI and then disable one of the cards to check any performance increase or decrease. With SLI I would also try “Alternative Frame Rendering” and “Split Frame Rendering” to see if that has any impact on performance.

Also unless the game engine can use both GPU's you are only utilizing 768MB on one of the cards not the full 1536MB.

As far as the system RAM (DDR2) is concerned, how fast the DDR3 is (just like with DDR2) is based on the speed the RAM operates at and it's timings, so yes there is plenty of slow DDR3 out there.

Since you are using an Intel Core 2 CPU I imagine you are using a motherboard with an Nvidia chipset (since you mentioned SLI) which supports a dual channel memory configuration and would require either two or four identically matched RAM modules to run optimally in dual channel. You mentioned having 6GB of RAM not 4 or 8GB which would lead me to believe that the RAM modules are mismatched?

Mike.

It almost looks like one of the video cards is causing visual artifacts, have you tried disabling SLI to see if the problem still exists?

[Redcoat_1812]

Dan,

many thanks for the advice and information. Yes the sys ram is not in a matched pairs config. Pc was bought with 2gb and then i purchased a further 2x2gb matched.

Although they are all the same type and speed of ram, which is 666mhz.

I will try disabling SLI to see if it makes any difference.

I am pretty sure that scenery is going missing on more than one route though, when run under OR.

Many thanks.

Mike.

conrail1 if it was a visual artifact I would doubt it would cast a shadow also, it looks like the terrain level for that spot got changed, I would run it in MSTS to see if it shows up there or not. If it does then a reinstall of that route would be needed, if not then OR is reading something wrong for that spot.

That's kind of what I was hinting to, with the motherboard supporting a dual channel memory configuration you'd ideally want to use either 2x2GB (4GB) or 4x2GB (8GB) modules.

You'd also pick some performance with a clock speed increase on the CPU. With 2 GPU's being feed by a Core 2 running at 2.7GHz you are right about the system being bottlenecked by the CPU.

Probably right, although I have seen video card's produce some very odd artifacts.
