Actually, your genes want both, since if you know you are the father then your genes can help direct you to giving more resources to your offspring rather than others. Indeed, there are plausible payoff matrices one can construct where one would rather have fewer offspring but be more certain which offspring are yours.
You actually don’t need to “know” which offspring are yours. You just need to direct more resources towards them. In fact not knowing a child is yours in a fiercely egalitarian culture might help you find good excuses for why you treat him preferably to other children. One just needs to “like” that child more for some reason and then the rationalizing mind will find ways to justify or conceal this preferential treatment.
A more finely tuned subconscious kin recognition system based on visual appraisal of facial features (if I recall right men do prefer children that are more similar to themselves) or perhaps something like smell might do the trick.

Correction accepted, but it doesn’t apply in the “fierce egalitarianism” scenario that Wei Dai mentioned.
Yeah, I agree. If one assumes near complete equidistribution of resources then it won’t apply.
