Problems with NT8 and Parallels

[waterchill]

Hi there,

I have some performance issues on NT8 with parallels. The crosshair is incredibly slow and if moving the chart window around it is extremely sluggish - not usable. If making the a chart window smaller it is faster, if bigger window, then slower performance. This issue is only on NT8, with NT7 is everything perfect.

I tried this with:
Parallels 11 and VM Ware Win 8.1 Pro and Win 10
Parallels 12 and VM Ware Win 8.1 Pro and Win 10
Parallels 13 and VM Ware Win 8.1 Pro and Win 10

Difference between VM Ware and Parallels is that VM Ware is much slower than Parallels.

Exactly same result on all varations. It is more worse if using coherence mode, the usability is an disaster. No problems here with NT7. Coherence is the mode i use daily for NT7 on all 3 monitors with 5 charts. One chart on one display and 4 charts on 2 displays.

My machine is:

Mac Pro 5,1 2x 3,46 Ghz 2x6Core
96 GB Ram
Nvidia GTX 980Ti 6GB#
3x 4K LG 31MU97 displays

If give more ram to Windows or more graphics ram, this doesn't matter. I read here that NT8 is using video card for display charts and NT7 is using CPU for this. So only way is to stuck in NT7 forever or is there a solution for this?

Hello,
I think If you intend to upgrade your Mac to mac-OS High Sierra and keep using Parallels Desktop for Mac, we strongly recommend you upgrade to Parallels Desktop.
Thank you

I'm already on 10.13 same problems were on 10.12 doesn't matter. I have already Parallels Desktop Pro edition.

waterchill, we do not have reports from all Mac users that they are experiencing this behavior, so I'd like to narrow this down a bit further:

• Does the issue occur if you use only one monitor?
• What is the resolution of this monitor? Does it occur if you use 1920x1080 resolution?

[waterchill]

The resolution is 4096x2160

I have just tested it. Disconnect 2 monitors gives a slightly better performance. Cut down the resolution to 1920x1080 gives a good performance also on three monitors. But this resolution is absolutely not usable for me. It seems to depend on the resolution.

The Development Team is actively working on making improvements to the crosshair's performance and also 4K/UHD resolution performance. The tracking number is SFT-1592. I've added details about your case.

Does performance change if you enable 'draw cursor only'? To do so, follow these steps:

• Right-click on your chart > Properties
• Expand 'crosshair' dropdown by clicking on the arrow to the left of 'crosshair'
• Enable 'Draw cursor only' > OK
• Follow these steps for all charts

Hi,

I tested it, doesn't make any difference.

Thanks for the feedback. I've added your information to our internal tracking regarding cross hair performance. This is being tracked as SFT-1592.
