The CPU will be swamped. I have the i5 4300 2.9 which is much stronger and has reliability issues running SSDR with one panadapter and JT-65. The real problem is the additional processes that are triggered by the O/S. If the CPU goes to 100% SSDR will starve for service and disconnect.
I will probably go to a desk top for my 6300. Too many crashes and weird experiences.
If you already have the computer then give it a shot but I would not recommend buying one to run SSDR.
Best of luck;
In one hand having the higher resolution will make for beautiful looking images in the display, but it will also tax your video card. So I am not sure how it will perform.
There are also several tweaks that you can do within the Advance Intel Graphics Control Panel (you can reach this menu right clicking on an empty space on the desktop and selecting "Graphic Properties", or by going into Control Panel > Appearance and Personalization > and search "Intel" which might be the easiest on Windows 8.1 [not sure of Win 8 menus]):
1. In 3D Sub menu, select "Performance" instead of "Quality". You can also try Custom Settings in that same menu and select "Anisotropic Filtering" of "x2" and see if it makes a difference.
2. Under Power Sub Menu select Maximum Performance while Plugged In
Please let us know if these settings improve the performance.
In my case an Intel HD 4000 wasn't enough to run 2 1920*1080 monitors and SmartSRD. So your feedback on the Intel HD 5300 could be of great value to colleagues looking for bare minimum specs on a new laptop.
Also, keep in mind that the guys at Flex are working on improving the software and maybe version 1.4 of SmartSDR will bring enough tweaks to graphics handling to make any video card discussion a moot one. :)
