Simd optimisations aren't very minor. For games anyway, we have a 90-10 rule (90% of time is spent inside 10% of the code) I'm sure that exists in other areas too. One of the most common operations performed is multiplying 4x4 matrices, which can get 300% speed ups with the correct simd operations. To get that speed up in the most called parts of your code is anything but minor |
