Hi all.
im an architect that trying to learn unreal for architecture visualizations vr with my htc vive set.
I already make it till now with enscape but i saw a Villa in unreal engine with thc vive and decided to start learning this from now on. Hope i could learn this.
I love to work with good computers and im looking for a specs to run unreal models with my vive at great perfomance.
Texture and shading (realizem) very important for me.

This is my current dektop computer:

GPU: Nvidia GTX 1060-6GB - 76.2%

RAM: G.SKILL RipjawsX DDR3 2133 C10 4x8GB - 50.5%

and thinking about this specs for my next desktop computer:

Can you help me and check this specs for Unreal VR. Do you change some of those ? make something better or use cheaper parts that could be just as much affective for unreal VR

Please answer - at list regarding the CPU & MBD. i have to decide wich to buy them in 2 days due to major discount i have.

Great thanks

Thanks for your response. i kind of new to unreal, i used sketchup + enscape for vr htc vive until now, and also autodeesk inventor + vred but after i saw some works here, i’m defenetly going to learn this. Hope i could manage this because i have no knowledge at c++ or something like this :), also the upcoming sketchup plugin to unreal is out and 4.20 will work with it.

so hope to make some beutiful things.

i will be looking to see your jobs. maybe we can help each other.
