I own the Slitherene version which does not offer this patch, I guess.
The Steam version only allowed for 1.3 open gL which is incompatible with others using 1.3.4.
Never had a problem until the last patch.
It works great on my WIN 10 at home, but I use a very good Win 7 (updated) for my other venues per lan parties.
Another friend, also, does this.
Neither of us could run the 1.3.4 version & his is a fairly new WIN 10.
