Friends,

I just bought the new 5K iMAC that came out last month. Here are the specs for my computer:

4.0GHz quad-core Intel Core i7
16GB 1867MHz DDRS SDRAM two 8GB
512GB Flash Storage
AMD Radeon R9 M390 w/ 2GB video memory

When I bought the new StarCraft II game, I went into the settings and upgraded the video display to the max. When I go to the play the game, the video scenes are severely lagging. Any issues? Should I just stick with StarCraft II defaults? Please help...thanks.

That's a pretty old game that my laptop with iris graphics handles fine. Though pretty much anything at 5k is going to be very taxing. Is the new expansion more demanding than the original game?

Did you set the resolution to 5K? That's too high for the graphic card. I suggest you set the resolution to 2560*1440. It should run perfectly fine.
If it is still lagging, consider install windows 10 using bootcamp and play games exclusively on windows.

Really? The computer is brand new, didn't realize the graphic card couldn't handle 5K display if it is in the computer.

4K gaming is a true luxury at this moment. R9 FURY or GTX 980 TI will probably get 30fps for latest titles.
5K display is almost twice the resolution of 4K. There is probably no graphic card in the world that could drive the latest games at 5K.

Your R9 M390 is a very very weak gaming card. You should run older games at 1440p and latest game at 1080p/720p.

Very very weak is a gross exaggeration. Most of the population uses the far weaker Intel iGPUs. Starcraft 2 should run perfectly fine on M390 at 2560x1440.

The GPU is enough for the 5K screen, you just can't game at that resolution.
 
even my gtx 980ti on PC can't do 60fps at max settings on 4k, I do 1440p. (not talking about SC II, I mean games like the Witcher 3)

Out of interest, how/why did you choose that particular graphics card for your imac, given that you weren't aware of how games and graphics cards work on computers?
