I didn't bother optimising, I just went with: S5, P6, E6, C4, I7, A6, L6, with good natured and small frame. Worked well so far.
I am not a huge min-maxer, but one thing I learned in the Fallout games is that a sniper needs a high Luck. Your critical hit chance is based on your Luck, and that is a what a sniper is all about getting. Try dumping a point from Strength and Endurance, and instead put the leftover points in Luck. Then look for items like the Recon Beret that raise Luck, or spend a few Intense Trainings on raising Luck even more. There are also traits and perks that raise your critical chance as well you can get.
I just looked over some of the weapon stats, and I see that FONV really nerfed the critical chance multipliers of all rifles. The FO3 Sniper Rifle has a Critical Multiplier of x5. The FONV version is only x2. So it is a lot harder to critically hit in NV.

Maybe it's because I'm only playing on normal difficulty, but I've really not had a shortage of critical hits. ED-E let me detect enemies long before I saw them, letting me get plenty of sneak crits. And up close 1st recon beret(raises crit chance and perception, not luck), Finesse, and That Gun got me plenty of crits. Throw in Better Criticals once I got it and I didn't come across much that needed a second crit. Anything that survived either got zapped by ED-E or punched by Veronica.
As for lowering strength, that isn't gonna happen. 5 strength plus implant and weapon handling lets me use the anti materiel rifle, and there's no way I'm passing that up.
Yes we do.


Seriously, FONV does not have very steep hardware requirements. Just about any computer you buy these days for $300 - $400 can play it just fine. You only have to make sure it has a real video card, rather than the usual intel integrated graphics garbage many come with. So you might need to pay an extra $100 for a video card.
Circumstances don't permit me to get even a mediocre gaming pc. And to be honest, I'm not all that interested. Consoles are far more convenient:
I buy a game for my console, I know that game will run on my console, no need to check specs to make sure.
No getting frustrated because a game I'm interested in is only available via Steam(which is an automatic no sale).
There's no shortage of places to buy console games(I'd rather buy physical copies of games from actual stores than buy online), the pre-owned games market here is huge, so I can pick console games up cheap, and trade in games when I'm finished with them, letting me save money on both ends.
Having been gaming on consoles since the N64, I'm more comfortable with controllers than keyboards and mice, removing one of the PCs advantages.
And finally, the only games I'd be interested in playing on PC are strategy games that typically aren't released on consoles. So it isn't even worth it.
I'll stick to my console.
