adobemaster Posted June 1, 2014 Share Posted June 1, 2014 Hi guys, i got one quick question. i tried to change the agpm kext so i could have better perfomance with my nvidia gtx275, but the problem is when i did that, i got even lower perfomance then before. (using CUDA-Z for comparison and the game dota 2) I changed the values for the treshold high-low and the device id, but you may have a better look perhaps if you check the atached kext file. Does anyone have perhaps any suggestions? I have read most of the topics here about agpm, but still i can't get it managed to work. Thank you AppleGraphicsPowerManagement.kext.zip Link to comment https://www.insanelymac.com/forum/topic/298372-agpm-problem-with-gtx275/ Share on other sites More sharing options...
artur_pt Posted June 1, 2014 Share Posted June 1, 2014 hello my advice is to use a legacy_AGPM don't mess with system kext AppleGraphicsPowerManagement (AGPM) for nVidia there it have some examples to use the legacy .. and also pre made legacy kext good hack Link to comment https://www.insanelymac.com/forum/topic/298372-agpm-problem-with-gtx275/#findComment-2023709 Share on other sites More sharing options...
adobemaster Posted June 1, 2014 Author Share Posted June 1, 2014 I downloaded the legacy kext for 10.8.2 and i changed in the info.plist the device id and the SMproductname, but it wont boot up now properly. Things i didn't change are the treshold values and i didn't change the device id in the system agpm kext file. Altought, it may be because i didn't install it properly perhaps. It's just a drop and drop of the kext in the kext utility right? Any suggestions @artur-pt?

adobemaster Posted June 1, 2014 Author Share Posted June 1, 2014 what do you mean by must use original agpm from system? i am using the original agpm kext, but i dont know do i have to update the device ID in the system agpm kext because it is not the same like in the picture attached to this reply. So to resume: -i must have both kext installed ( system agpm and this legacy apm) -both kext must have correct device ID for the graphic card (because the device ID in the system kext is wrong according to the system info) Am i correct?

adobemaster Posted June 3, 2014 Author Share Posted June 3, 2014 well, it doesnt matter i think because with both kext having the same threshold values, i'm having excellent perfomance in games so i think the gpu is working fine now. The problem with dota2 was it's not developed well for now. Thank you very much in any case @artur-pt Link to comment https://www.insanelymac.com/forum/topic/298372-agpm-problem-with-gtx275/#findComment-2024321 Share on other sites More sharing options...
