DCS on Surface Pro 4

For demonstration purposes, I installed DCS on a Surface Pro 4 with 8 Gb main memory. The graphics adapter has 4Gb memory. As soon as the sim starts, only black and white is visible outside the cockpit. The only objects visible are white clouds on a totally black background. If a shadow hits an object inside the cockpit it is covered by an opaque, black shadow. Has someone the same problem and solved it probably ?

The Surface Pro 4 Uses IntelHD Graphics,

 

Which is NOT Supported.

 

That 4GB of VRAM comes from the 8 GB of System Ram.

 

So you're trying to Run DCS w/ 4GB of Ram on a Unsupported GPU.

Windows 10 Pro, Ryzen 2700X @ 4.6Ghz, 32GB DDR4-3200 GSkill,

X470 Taichi Ultimate, R7970 Lightning @ 1.2 / 6 GHz Memory

3x ASUS VS248HP + Oculus HMD, Thrustmaster Warthog HOTAS + MFDs

Sorry for answering that late. Christmas stress.

After reviewing all the symptoms, I came to the conclusion, that there must be something wrong with texture transparency. All the shadows, even in the cockpit are opaque. The outer scenery is always covered with mist of different strength, which can be a transparent texture or a fog function in DirectX. Since we have no mist or fog in a cockpit, all the cockpit scenery is displayed as expected. As long as no shadow covers a cockpit object. It does not explain the source of the bug. I assume a bug in the DirectX layer which must be made especially for the Surface 4 GPU. The technical description of the i7-6650U CPU does not specify, that it shares graphics memory with the main memory area. The CPU and the embedded GPU can have 32 Gb each as maximum. DCS seems to handle the Fog function correct, because it works on other computers. So, I will have a look in a Surface 4 Forum. Probably somebody else observed a similar bug.

Thanks for all answers…
