Frame Rates in Open Rails

[Sasmit Singh]

i have fps 12 is it good for running it or not.

The answer should be clear to you when running (or attempting to run) OR: Not.

Personal experience: i5 laptop with Intel graphics & 4GB RAM - is (barely) playable at 15-25 fps, but in complex areas it drops below 15 and strange things (the random slip problem noted in this thread FROM 6 1/2 YEARS AGO, among other things) make game play impossible.

Please start a new thread of your own to ask more specific questions rather than resurrecting an ancient one.

So true Mike,
Pardon for adding to a six year old thread. Remember "Moore's Law". The poster Sasmit Singh is talking ancient history!

And btw, all you folks boasting of triple digit frame rates does absolutely NOTHING! as the video can ONLY be displayed at the monitors maximum frame rate, usually 60 to 80 FPS. Even interlaced video. You can't syuff 100 gallons into a 5 gallon container. PooF

Setting your Open Rails >Options>Video to "Vertical Sync" will result in smoother running Sim for most video cards.
I'm not so sure about On Board (integrated) Video that shares (and takes away from) your system memory.
It used to be so simple in MSTS where you could get away with that as video was largely processed by the CPU. Not so any more.

After all, you can try to stuff 100 fps into a 60 fps frame rate monitor but the monitor cannot physically accept it so you've got 40 fps of wasted Machine/Video cycles as the video card tries the impossible but cannot accept it.
The smoother running comes by way of the Video Card not having to make repeated attempts to pump video to the monitor but rather waits for the time when the monitor CAN accept and display video data.

Thanks Vince, great advice

I gave it a couple of tests and stated FPS were from 200 - 400 but
occasional jitters, with Vertical Sync on it was 60 FPS but smooth as the proverbial....

Frame Rates ( FPS ) are what the video card can produce and are shown by the Refresh Rate ( Hz ) of the monitor . The Refresh Rate of the monitor is the limiting factor and the better video cards can produce higher quality video at superior speeds to basically over supply the monitor . This gives a much smoother picture and at much better quality , depending on your card settings . A high quality example would be a 300 FPS with a 240Hz monitor .

I didn't know these things existed ( I just Googled ) but should have knowing the advances in the industry so thanks for the info.

Evidently letting the video card free run into a 60 - 80Hz monitor is as I suspected, a waste of time and here Vertical Sync is a good way to smooth things out.
I'd bet these monitors are pricey little devils tho'.

Thank You for the Vertical Sync info!! That really improved the visual performance, and i can tell the fan speed is way down as well! Thanks again!
