I'd like to know who does not use MV_Advanced.vp and why. Is there a very specific reason for that or do you experience slowdowns when you use MV_Advanced.vp? Note that FSO 3.6.12 has significantly better performance than 3.6.10, if you have previously dismissed MV_Advanced.vp due to performance reasons, can you please try again with 3.6.12 RC3.
In addition, if you have poor performance with MV_Advanced.vp, please also try MV_AbolishAnimGlows.vp with MV_Advanced.vp. It can be downloaded from sticky mediavps release topic.
I've begun to question the need for beam warmup particle effects, muzzle flashes, beam piercing effects (only in fsu svn at the moment) and so on to be in MV_Advanced. From what I've seen in BP2 beta-testing, all those seem to have minimal, if any performance impact in FSO 3.6.12. If this holds true to rest of the community, then MV_Advanced is only good for holding animated effects and maps as well as higher-resolution effects and maps.
Which means all effects could be in MV_Effects.vp, while MV_Advanced only makes them better looking.
