TP4 with crash, glitch and freeze -> check that !

Spekulos

Hello,

I found something interesting about crashs in TP 4.

The first time, i go a freeze with a horrible glitchy sound continualy generated (the only solution was to hard kill TP4 then restart). So i put the buffer to max (1024).

Then i constantly got unexpected crashs (TP4 close by itself without error message, just returning to windows sudently).

In fact it was totaly unusable in live condition.

What surprised me is that it is working fine with a lot of peripheral connected to this same computer, and particulary with a second monitor.

The culprite was quickly identifed : GPU SWITCH.

I searched for other posts concerning crashs with TP4 and they seems to have the same configuration : Internal GPU muxed with External GPU.

When a second monitor is connected, it automaticaly force the use of the second gpu for all application (this is a hardware limitation), and TP4 never crash in this configuration.

So i forced the use of the external GPU for TP4 executable in windows and now everything is working fine, even with low value buffer.

Clearly, sometimes the GPU switch from integrated to external during TP4 execution (probably in high load condition) and it create unrecoverable interruption in the software (or i think something like that).

My config : Windows 10 pro - Ryzen 7 4800H(with integrated gpu) + Nvidia GTX1660ti

I am curious to have the advice of NI guys or professionals about that.
