It depends on the candidates.

If you like or are neutral to candidate X, and dislike Y then voting even if it's pointless still feels good. So, win or lose voting still feels good.

If you dislike X, but dislike Y more then voting feels painful. If you think it's close then you are more willing to go though that pain. But, if you think X will win and you don't want to vote for them then there is little downside to staying home. On the other hand, if you think Y is going to win then you can say to your self it's not a vote for X, it's a vote in protest to Y.

Granted, if you dislike X, and hate Y or have something else you care about, like voting in every election, and are in the booth anyway then that's another story.

Now, this is probably not a huge effect but, in states that where within 1% it still matters.
