all known issues.
Tractor beams / Pulsed Grav beams - yeah, bsots allows them to be more places and they can become silly. I tend to play to a certain point - where the game becomes tedious for me - and start a new one. lol - not a great solution, but that's my solution. You can always disable certain techs by messing with the mastertechlist.tech file - simply comment out all of the 'allows' lines that lead to the techs you don't want. E.g. "SLD_Intang" is unreachable in BSOTS - there aren't any "allows" lines that lead to them. Do the same for plused grav beams or/and tractor beams and you'll remove them from the game, if that's what you prefer. NOTE: TECH CHANGES ALWAYS REQUIRE A NEW GAME!
The pink/black texturing is probably related to memory constraints on your video card, or possibly a bug in the video driver. Either way, it doesn't happen earlier in a game or on a video card with more RAM (I haven't seen it since I moved to a 4gb video card).
Super large battles - happen late game in large enough galaxies. Yes - you're just running into address exhaustion for a 32bit game. You can use something like 4gb_patch (http://www.ntcore.com/4gb_patch.php
) which can force mars.exe to be recognized as being "4GB aware" - instead of the normal 2GB limit for signed 32bit values - but ... that may or may not help. Most software needs to be extensively tested and written for 4GB awareness for it to work properly. Still - it may help some. NOTE: YOU MUST DISABLE STEAM'S AUTO-UPDATE OR ELSE IT WILL "FIX" YOUR MODIFIED MARS.EXE AFTER YOU PATCH IT TO EFFECTIVELY UN-PATCH IT!
You can of course reduce the late game exponential growth of all things by playing on a smaller map.
Yeah, ultimately it would be sooo nice to have a way to fix old games to properly use all 32bits instead of 31bits for their addressing - but most programs - even leading lights in the field - still argue for using signed numbers always unless absolutely necessary - which to me is just wrong. unsigned for all addressing needs - and signed only for mathematical computation (excluding addresses). /soapbox
Until then, we just have to find ways to have fun within the limits. You may find some more relief by disabling some of the higher rez skyboxes for battles, if you don't mind losing visuals? or there are some controls for graphics in the games options panel that you can reduce (reduced visual distance may speed things up, not sure it helps with VRAM exhaustion?)
