slow performance with new laptop with RTX3000 Quadro 6Gb

Hi everyone,

 

 I have very strange performance issues with SW2020 SP1.

 

I just bought a new laptop, an ASUS CONCEPT D with 32 Gb of RAM, 1TB SSD, RTX3000 6Gb graphic card.

 

I7-9750H processor and a 4k screen.  In short a very powerfull laptop in my eyes.  I am using it for almost 2 months now but have alot of performance issues like viewport lag, crashes... if I open 5 simple (max 1 Mb) parts at once it's out of memory and SW works extremely laggy.  

 

I have changed all the settings in the Nvidea control center, so SW uses the RTX3000.  I have the latest drivers and had multiple contacts with my SW reseller about this.  

 

As soon as I start a new part, the memory usage of the RTX3000 goes up to approx 4Gb!!

 

So what have I tried just now.

 

I deinstalled my nvidia driver for the RTX3000, restarted windows and ran SW again.

 

And I couldn't believe it,  but all my problems are gone. 

 

I can open 25 parts, assemblies at once and work with them without problems.

 

Please have a look at the attachment. (I also included English text)

 

In the first screenshot you can see the problems with the RTX3000 card when opening only 5 parts at once.

 

In the screenshots afterwards, you can see I disabled the RTX3000 card (since windows installed it back automatically after restart) and it works like a charm..... without my expensive RTX3000.

 

What could be this issue?   I can not be true that an onboard GPU has much better perfomance than my RTX3000???

 

All help is appreciated, :-)

 

Best Regards,

Frederick
