I just fed DCS with another SSD. And it was worthy.
The long awaited 2.5 engine was release last week and it features some radical improvements over any of the previous versions.
In the video below (please ignore the hicups due to my usage of a regular hard drive) you will see that is not just the looks. Performance is better, the trees are collide-able and non-transparent to computer-controlled units.
And yes, the feeling of flying, fighting and bombing over a real place has never been like this.
That video is from a flight over an scenario that I hope to release in the future.
