Anybody else have this problem upgrading to Open Rails 1.5.1 ?

[motormaster532]

Dont know what to make of this. My Alienware 14 which normally gave me Frame Rates of 60 to 80 when running most Routes in Versions up to 1.5.1 now only gets me mid to lower 30s on Version 1.5.1. I have to admit that the computer is a bit old and my Memory is at the Upper ranges of used,but I still cant figure out why,especially as I found Version 1.3 sequestered someplace in my hard drive and re-tried it, Went back to the range of 60 to 80 again. If anybody can tell me why and a possible correction, I would be VERY thankful. Brian

Going from 1.3 to 1.5.1 included a LOT more code, so I am not surprised it has slowed down.
I only use Carlo's version, so I have not used 1.3 since 1.4 came out.

I briefly tried 1.5.when it was first released but rolled back to to 1.4 after some of the 1.5 bugs became more than I cared to tolerate.

Thank You Derek and Dave. I too was using 1.4 and delayed the upgrade due to the "Auto" upgrader not working. I recently bought a new Alienware computer and out of laziness have not yet fully installed all my Open Rails stuff and TSRE on it. The 1.5 is on that one however,and it will be interesting to see what FPS is on that computer. I would prefer to go back to 1.4,but the upgrade swallowed that version,so I guess i am lucky that a found the 1.3 buried somewhere,so i will use that. Once again thanks' guys. Brian

Make absolutely sure that the appropriate graphics card is being used by OR. Most alienware computers ( well, at least mine does ) have two cards, an Intel and usually a Nvidia...with Win10 you have to go through some contortions to make sure OR is always using the Nvidia...if it is using the intel framerates will plunge.

Thank You Jerry! I never upgraded this computer to Win 10-still using 7,but my new one,which I am taking a year and a day to get online has 10,so I make sure that I keep your advice in mind if any problems! This problem occurred when I went to 1.5.1 and even when I was able to go back to 4.1,the problem persists. I must say that my Memory is almost at its maximum and I know that is adding to these problems. It is time to either add more memory or get the new one up and running. Thank You. Brian

I use the Nvidia Control Panel, but with Win10 you also have to go to the System \ Display \ Graphics settings \ Graphics performance preference to choose the correct graphics card for a specific program. And I've had some Windows updates change my selections.

I must apologize for mis-spelling your name, Gerry!

Nonsense! Kind of you, not necessary, I'll answer to Hey You.
