for me its the same when running on my laptop , settings things to low especially terrain causes some things to glitch

okay but here it is , only prototype thought http://techcrunch.com/2012/01/31/self-guided-bullet-could-strike-laser-designated-targets-from-a-mile-away/

This : guided bullet sniper rifles http://www.newscientist.com/article/dn23571-selfaiming-rifle-turns-novices-into-expert-snipers.html now that is too easy , removing all the fun from sniping , but totally realistic . Bipods and Weapon resting should be top-priority , there is a mod for that , but this feature should come in vanilla

Well this should be definitely in-game at least for special forces , i saw pictures of vehicle with railguns .. now that is sci-fi ( railguns require an huge amount of energy ) Future Force warrior ( USA ) , GLADIUS ( Germany ) , Soldato Futuro ( Italy ) , Ratnik ( Russia ) ... those systems are current tech ( look for example Google Glasses ) and will only improve in the future ( probably contact lenses instead of head mounted display )

22 years is a lot of time ... especially in electronics , just think how were computers 22 years ago and what they can be 22 years from now even if they're 'greatly developed devices' thermal sensors and NVGs have improved a lot , in the future smaller devices will be more and more capable like current bigger ones ...its only a problem of miniaturization , probably a thermal optic will have the same specifics as a current vehicle one.

Also do not forget that Iran now has a 'time machine' , that's why they're so advanced in-game , in the Armaverse this thing apparently seems to work going against physics . http://www.telegraph.co.uk/news/worldnews/middleeast/iran/9985757/Iranian-scientist-claims-to-have-invented-time-machine.html

Higher velocity means only higher energy , how and how much this energy will be transferred to the target ? In some cases even a slower bullet could be deadlier than a faster one because it will transfer its entire energy while the faster one could go throught the body exchanging little energy.

you could assume that in 2030s Throat microphones and/or Subvocal recognition are more widespread , hand signals would cool anyway but like metalcraze said are difficult to implement.

Well, top-notch body armour can take multiple shots from 7.62×39 right now, now considering the game set is 2030s and the advancement of nanotechnology and science material , a conventional pistol or smg bullet will have an hard time to penetrate such thing , then add the adrenaline factor .

oddly tank-mounted railguns sounds more like 2142 than 2030 ... ( unless someone could come up with cold-fusion or Iron Man's Arc reactor ) Hard-kill, soft-kill countermeasures seems are confirmed Guided tanks shells also could be a nice addition But as someone has said before , the most of the vehicles is totally unknown ( Iranian jet for example )...so at least we need to wait for the beta .

it would be cool also if you can swap the barrel and the upper receiver , thus allowing to change ammo type and barrel lenght . By now your only option is to carry two rifles. Just take some inspiration from RPGs inventory systems ...

this should be a priority together with weapon resting ... it totally ruins the gameplay

its a difficult problem to resolve but check this it is a graphic engine which use fractal algorithms to render grass and objects at distance with low resources. If BIS engine or a mod could do something like that, this problem could be overcomed maybe. By now sinking with the grass layer technique and improved mid range textures , seems the best workaround . Also the blur the soldier thing is very interesting .

this!... its like a sort of advanced javelin.
