It's been a long road, we're almost there, and we felt you deserved a small Christmas present for your patience and so a short while ago we released a Public Preview of GameGuru which you can access through your Steam Client > GameGuru > Properties > Beta dialog which switches your current version over to a test version which shows off the new DirectX 11 engine and PBR rendering, including an updated Big Escape demo level that includes new PBR game assets.
We have released this preview in order to get a wider range of feedback on the current internal build and make sure the performance, visuals, backward/legacy compatibility are solid before we release the final update to you. This allows you access to the DirectX 11 overhaul if you want to try it out, but keep the current version while your fellow community members test it out.
The feedback so far has been positive, with reports of much faster boot times, and for some users a faster in-game rendering performance. Both loading and general performance will continue to be worked on in 2018 so feel free to try the Public Preview (remembering of course to make plenty of back-ups of your game projects and custom media) and report anything you feel should be included in the final update.
We are also excited to announce that the Steam Winter Sale is on right now, and we have a special Christmas treat for anyone who has yet to take the plunge and try out GameGuru. If you check out the main GameGuru Steam page and scroll down, you will see plenty of discounts we've arranged for you, including the Sci-Fi and Fantasy Bundles:

From the GameGuru team, and all of us at The Game Creators, may we wish you a Merry Christmas and hope to see you all again next year as we continue to develop GameGuru into something very special. Take care everyone and happy game making!
