Hello Diogo, Ricardo,

I want to use 2048 cache size with my project but i have some small freeze (more than 500ms for AT-Prep)

I tried with different gpu (geforce 770, 970, 980, titan, quadro k5200, quadro k6000 and quadro m6000) and i have the same problem with all of them.
Do i misconfigured AT2 or there is something i need to do or there is a problem with 2048 cache size ?

PC used for testing : 16go ram (DDR3 2133), SSD drive and I7 4770k

Cheers,
David

Hello David,

Do you experience the same issue on ATI GPU's? Are you targeting DX11 in your builds or lower specifications?

Thanks

I was testing with a unity 5.1 build (standalone windows x64 dx11) and the problem is less visible (with a quadro K5000) than in editor. I think it happens when you are loading new VT on screen. I'm using 8 VT for my project (from 6 to 10 go each).
I did not see any freeze when we fly over the same VT but as soon as we are moving between 2 or 3 VT, it happens.
