Unity not using my dedicated gpu

Hello,

I have recently started looking into Unity and have just completed one of their tutorials called the Survivalist Shooter Project. Whenever I run it I start off at about 60-70fps but after a few seconds it starts to drop, even if I do nothing. It eventually settles at about 3fps. I have a GTX 750 ti which can run games such as Total War: Rome 2 on max at 60fps. I fail to see how this small unity game requires more power than simulating armies of 1000's crashing into each other.

One strange thing I have noticed with my GPU is that I don't have the option to set it as my default graphics processor via the Nvidia control panel.

Full specs:
Windows 10 64bit
i3-4170 3.7GHz
8GB ram
GTX 750 ti

 

Do you have a bug report number?

 

How would I find this out? I am very new, sorry if this is a stupid question

I think I found the problem. I had an error in my code running every frame. You might as well delete the thread. Thanks for the reply.
