emporer battle for dune lag

[bmdkks]

Hi

I installed Battle for dune and patch 1.09. It runs, but there is a lot of lag/it has low fps.

I ran it in borderless windowed which helped tons, but I can't crank up the graphics quality. On low gfx setting fps is fine and game very playable, but it lags when I push it up. Low graphics in fullscreen also lags, so windowed definitely helps, but only at low gfx. Any ideas why or how to fix it?

Windows 8.1 with latest updates

i5 2520m 2.6 ghz (3.2 ghz) dual core

AMD Radeon HD 7670m/Intel HD 4000

6gb ram

The game runs on my amd,. I haven't tried it on the Intel yet. Will update once I've tried but I'm not hopeful.
