Get over it

Honestly, the noise from the shot would only tell you that there is someone shooting... And maybe a cardinal directions, maybe. Not enough to get you spotted with any kind of expediency.

I did say an idea, not a direct location

Yeah I guess, but the matter at hand is whether the noise would ultimately effect their camping, which is incredibly unlikely

A muzzle flash on the other hand would get ya dead real quick

There is no making you happy is there?

A suppressor would get rid of most of the sound and would hide a lot of, if not all, of the muzzle flash.

No reason not to have one on anyway.

True, they can also help reduce recoil

At the cost of reduced range, penetration, and damage.

Not always actually, videogames usually do that so there's a bit of a trade-off for using one, and though it is possible they might decrease the bullet's speed by a bit, it's pretty negligible. Being hit by a slightly slower bullet is still being hit by a bullet, and if you can survive the shot from one you can survive the same shot from the other, and vice versa. So, with the reduced recoil I mentioned above and the increased accuracy that entails, you're actually more likely to make a better shot

While being hit by a slower bullet can cause it to keyhole the wound, I would argue that response time from the bullet actually hitting the target rather than adding delay would be more important except in certain situations. While precise speed might not seem like a important factor, you underestimate the killing power of a slug half the size of your finger going through you at 3,500 feet per second. It isn't a force to be downplayed. Recoil also doesn't matter that much when you're not firing off a shot every half-second. Much of the issue with games is that you want to be able to fire as fast as you want, but it would only work within the boundaries of that game.

I understand what you're saying, but a piece of metal traveling even just a fraction of that speed could still kill you, probably even a fraction of said fraction could still get the job done. Also recoil definitely affects accuracy, especially with faster bullet's. When the bullet travels through the barrel the rifling will actually cause the gun to whip around in a circle, reducing accuracy.
