Time Step Limitation in Multisim Live for Real-time Interactive Simulation

I'm trying/learning Multisim Live by setting up some basic circuits (starting with a classic low-pass RC circuit) and want to see a real-time graph running an Interactive simulation.  But the maximum time step it's letting me set is 1e-5, which isn't real-time (about half real-time).  Going under that time step (<1e-5) makes it run even slower.  When trying to manually set the max time step higher, I get the error:

 

"maximum time step must be a number between 1e-12 and 1e-5"

 

Am I missing something with the configuration and setup of the circuit or simulation?  For the circuit, it's fairly simple: AC voltage source, SPST switch, 1 resistor, 1 capacitor.  Both source and capacitor are grounded.

 

Better yet, is there a setting to make all interactive simulations plot/graph in real-time?  Totally okay to sacrifice resolution or accuracy - just want to be able to see values fluctuate as if I have a breadboard and multimeter in front of me.

Поставьте стационарную версию, которая вам посчитает процессы длительностью 500 Мегасекунд за доли секунды. Только не пользуйтесь осциллографом,-он всё изгадит..., а пользуйтесь трансцендентным анализом.

Thanks for the help, and for others that are curious, this is what tipa said, according to Google Translate:

 

(Translated from Russian)

"Install a stationary version that will calculate processes lasting 500 Megaseconds in a fraction of a second. Just don't use an oscilloscope - it will spoil everything... but use transcendental analysis."

 

Your proposed solution seems like it would work for Multisim on the desktop, but I'm using Multisim Live - the online browser version.  So I'm unable to change Tmax like you were showing.  Is there a reason there's a limit on that for Multisim Live, or is there another way to get real-time graphing?

I think that the developers of Multisim, subject to the availability of high-speed Internet, will be able to help you, although this is unlikely ..., because, even in the simplest matters, they do not help much ...
Удачи!
