Illustrator on Horizon View v7

Question

Hello everyone,I'm running a VDI proof of concept of the Horizon View platform and have a few Illustrator issues that I am trying to bottom out. I'm not an expert on Illustrator at all and dont have time to get a complete technical understanding of the product so I'm trying to pick my battles - please bear with me! Issue 1 - Illustrator/Clipboard/PerformanceThe (Windows 7) VDI is comprised of a few persistent dedicated desktops - meaning the virtual desktops are allocated to individual users and any changes or settings will persist and still be there after the user logs off.Adobe CCS Illustrator is installed onto each of the desktops and the ESXi host the VDI estate is sat upon has nVidia M60 GRID cards installed with 2GB vGPU profiles allocated to each virtual desktop, I also have 4vCPU and 10GB RAM allocated to each desktop and local SSD storage in the host is delivering the IO performance the VDI needs - so resource should not be an issue. The first issue I am trying to understand is with the clipboard on the VDI - as the user pastes data to the clipboard from Illustrator the Illustrator application slows down, purging the contents of the clipboard (cmd /c “echo off | clip”) brings the performance back again but I'm interested to understand why this happens on VDI and not on the customers desktop PC's that run Illustrator?Issue 2 - Too much grey!The second lesser issue I'm hoping can be resolved with tweaking the Illustrator preferences, the attached file illustrates the problem:Dropbox - Test.pdfThe left hand image in the file shows a background of various shades of grey when it should be white (as per right-hand image). The grey issue also depends on the level of zoom, are there any users of Illustrator that can quickly point out the preferences that might affect the way the image is displayed?My sincere and profuse thanks in anticipation!Adam

Presumably extra memory operations from the VM. Either the content is pushed to memory ranges that would not be used on a physical computer or it's generally moving stuff around to maintain the VM's base parameters - after all - copy&paste data can easily take up gigabytes. You only need a single heavy pixel image and then file I/O to the VM's disk-based caches can kill you. Also check stuff like VM recovery/ state backups. Again, too much clipboard data may simply bloat the process and slow it down.

There's nothing to tweak. I see no greys, I simply see a lack of color management/ broken color profiles. You need to make sure your VM emulates a proper monitor and of course you also have to provide access to all ICC profiles that any of your artwork files may use. That and working hardware acceleration in AI as well as for accelerated CM on a system level. Your example simply looks like it was created on a machine with a specific profile and that info is persistently stored in AI files. Chances are the artwork would look rubbish on other computers as well without those profiles.
