Lag Or Drop in FPS

[The rock]

Whats the Problem?
Suppose I have increased the throttle, the train runs smoothly for 2-3 seconds and all of a sudden there is a drop in fps. Again within a second, it runs smoothly and again fps drops. It goes on and on. Can someone state the solution to it.
My Laptop specs:
Intel i3 5010U @2.10 GHz(Quad Core)
Nvidia GeForce 930M 2GB and Intel HD Graphics 5500
Ram 8GB.

Likely to be disk access, replace hd with ssd.

How can my HD Drive be the problem? Is it because my laptop specs aren't strong?

The specs are a little light, but not horrible. Disk transfers can be a problem, especially from a laptop hard disk that's slow for power management purposes (and usually can't be fixed without changing out for something else which, if not SSD, might reduce battery life).

Another possibility to check is whether the nVidia GPU is actually being used - some laptops don't automatically switch when using Open Rails, so you might need to add OR to a list someplace of games to use the nVidia chip, or might need to activate the nVidia chip in the BIOS (it's usually not activated full time because Intel graphics use much less power). Intel graphics are known to severely limit fps for Open Rails. I think OR can tell you what kind of graphics are in use, but don't remember where.

Thanks, it actually worked. Apparently, OpenRails was using Intel Graphics as default, so I changed the software's default graphics processor to Nvidia.

How did you do this?

Hi bprice,
If your PC has two different graphics systems, you can usually switch between them using the BIOS settings. You might also find you can switch within Windows but it all depends on how your system is set up - the manual could have the info you need!
