Thief '14 was crap... well, at least very underwhelming, but fret not my dear taffers!, as the free, and awesome Dark Mod got a new update!, 2.03 to be precise!, so if you already have it installed, just fire up "tdm_update" in your installation folder, let it download around 350+ mb and you're good to go!
And what does this new update bring?, well, to sum up, it brings lots and lots of new optimizations, like adding new Level of Detail rendering techiques -NPCs get a reduced detail model at a certain distance to help alliviate the performance, a pretty common technique in almost any game- and also some much needed AI improvements, like guards actually working together to look for you, like sending some guards to certain choke points to hinder your escape routes instead of tripping over each other like headless chickens.
Graphically speaking, it also got an improved particle system to look nice and play well with your gaming PC (less framedrops) and it also got lots and lots of improved and new high quality textures and models as well.
So yeah, not bad for a former Doom 3 mod, it looks a lot better than Doom 3 itself (by far) and it certainly looks a whole lot better than that abherration of Thief '14. Check the mod out if you haven't, it's completely free and it's stand alone, meaning you don't need Doom 3 to enjoy it.
Although the download itself is just a tool set of assets, not a "game" per se, so you need to download some fan made missions to play with. My personal recommendations are the default level "Tears of St. Lucia" and the "Requiem" level, it's so big you'll probably finish it in 4 hours, I'm not even joking!, this could very well be 3 to 4 entire levels by itself!
Happy taffing!
