If you are using and AMD RX series or new card (this could affect older models) there is a driver bug that causes severe Corel Draw 2017 performance issues. I was running AMD Adrenaline 17.12.2 and I tried the latest version 18.1.1 and both rendered Corel Draw 2017 useless. I uninstalled both driver versions and reverted back to the Microsoft update service driver version 17.50.15.01-180112a1-322990. Corel Draw 2017 now opens, edits converts files perfectly fine again.
My system specs:
G.SKILL 16GB DDR 2400 memory - F4-2400C16D-16GFXR
512GB Plextor M.2 M8Pe(G)
Had to go back to 17.7. Driver 18.1 opening saving exporting makes computer sluggish.
i7 3770K, Dual R9 290X, 32GB Ram, 840 evo 512GB
17.7 WOW You can see from my post the Microsoft update service driver is 17.50.15.01-180112a1-322990.
I uninstalled driver and Windows 10 put this on. I am checking under Radeon settings system then overview. Device manager shows driver 18.104.22.1689.
