    Ok which of these two Dwords is the correct Dword to reduce FQS in registry? I've read older posts that say
    -Change Main3d from 33 to 31
    -Change Main3d_Def from 3 to 1
    -Add Dword FlipQueueSize and add 1

    Need some clarity on this?

    IMO the Valid one is Main3d=33 (3 Frames ahead from CPU)
    FlipQueueSize is not avaible for some time or it's replaced by Main3d.
    Don't know for sure, need to ask driver team.
    Maby it's placebo thing....

    Best settings for Main3d
    Weak CPU = 1
    Good CPU= 2 or 3

    I have default on this, every game working like a charm :p

    "KMD_PrimitiveShaderSupport"=dword:00000001
    "PP_ODNExMaxACTimingTuningLevel"=dword:00000002
    "KMD_USUEnable"=dword:00000001

    \0000\UMD
    "FlipQueueSize"=hex:31,00
    "Main3D_DEF"="3"
    "Main3D"=hex:33,00,00,00
    "ShaderCache"=hex:31,00

    D3D9 perhaps but I'm not sure, thought AMD set it to 1 in D3D10/D3D11 in newer drivers but maybe I can find something.

    Tried them (Main3d and FlipQueueSize; you might want to try 33,32,31 with FlipQueueSize also) in games. You can never know what someone from AMD decides to do with those registry keys.
    In some cases you will see improvements, in some cases you will see things being considerable worst.
    It depends on game engine, driver version, windows version, hardware you own and how well you are capable to notice the stutter.
    In some cases you might find out that 2 is better than 3 or 1.

    If someone is telling you that there is a magic setting that work perfect in every single scenario that person should be ignored because it has no clue what he/she is saying (but well we do live in a world where someone that has no clue about what he is saying and doing can easily end up president of a military powerfull country).
    Something that works well/good in someone else case might just not work at all in your case. You can't just jump on conclusions when the number of samples you can test are extremely low, you need a huge amount of samples (that you yourself have to test) to come with global affirmations (even then if you have some sort of brain you will admit there can still be exceptions from your affirmations, but what do I say here, we have reputable scientiests that are unable to understand that there can be exceptions).

    Thanks for the responses.
    Ok this is for DX11 and DX12 games. Does FQS/Main3D work and if so which one?
    If it's FQS is it in the same location as Main3d?
