    There was no callgrind just plain pts and the resolution was 1366x768. 136x768 is obviously a typo :rolleyes:

    Yes you are spreading baseless claims and when I told you it was basically impossible for my patch to have an effect on the game you were magiclly benchmarking by eye you claimed that callgrind was...

    Do you have results from the avx2 code? I'd be interested to see how different it is from sse4.1. I can't test myself as I don't have a cpu that supports it

    Some people have come here to learn its clear from your last two posts that your just here to spread fud.

    SSE works across x86 cpu's that support the various versions and intrinics work across...

    Yeah I think geearf read the post I linked to which talks about using the -O3 flag to auto generate this type of code. I meant that as example that its not easy
    for gcc to make these kind of...

    Yeah thats what it will be :)

    Sigh. No I already posted that I ran callgrind+extremetuxracer and the function that I made changes to was only use 0.04% and only called just over 1200 times which is nothing. I did see other areas...

    To use your own words, I'm not impressed by that benchmarking technique ;) As I said previously the function in question seems to be hardly used at all in extremetuxracer so if you are really seeing...

    If anyones interested I just got sent an email pointing me to this post [1] about auto-vectorization in gcc i.e automated use of SSE/AVX.

    There are likely to be at most 3 targets for this...

    Just because SSE2 is enabled doesnt always mean gcc will know when its best to use it.

    @dungeon

    How exactly are you running the tux racer as a benchmark? I've tried:

    etr -a

    on fedora 20 but it doesn't do anything it just opens the game as normal.

    Update: Also how are you...

    This is a long shot but does changing the first if statment from:

    if (aligned_count >= 4) {

    to

    if (aligned_count >= 8) {

    help at all? If the array size was 4 through to 7 then the patch...

    There has also been an alternate SSE2 version posted to the mailing list: http://lists.freedesktop.org/archives/mesa-dev/2014-October/069886.html

    Thats correct I hadn't explained the issues I was having, and moved on to working on other things. So much to work on so little time :-(

    Out of interest what do you sugget as an easy fix? I may...
  15. hmm ok, how many times did you run the benchmark?...

    hmm ok, how many times did you run the benchmark? It can be hard to get consitent results sometime. Just looking for an easy answer :)
  16. Hmm, it could be as leonmaxx said the frequency...

    Hmm, it could be as leonmaxx said the frequency is dropping due to a lesser load, but I would have thought that would caused a bigger drop in framerates. I'll take a look at extremetuxracer later on...

    Its mostly done I've been waiting for reviews of my latest piglit tests before pushing to hard with the Mesa changes. However, the dev's are busy and are taking a while to getting around to review.

    Out of interest. What did you benchmark and what were the results?

    Also what cpu/gpu did you test with?

    No need to get so upset. It could have been said in a nicer way but you really didn't specify what you wanted help with. Are you just trying to configure the drivers to get the most out of them? Or...
