cyberderf Posted September 8, 2015 Share Posted September 8, 2015 Hi all. Here are my specs : 2,13 GHz Quad-Core Intel Xeon 8 Go 800 MHz DDR2 SDRAM NVIDIA GeForce 8600 GTS 256 Mo Yosemite 10.10 SSD Drive Safari an Chrome browser Yosemite responsiveness is OK. But web page rendering is sometimes slow (scrolling is not that smooth) and flash and html5 videos are eating a lot of cpu (near 100% sometime). I was planning on getting Nvidia GTX 750 to remove some load of the CPU. Do you think it would make a noticeable difference? Any idea to speed things up a bit?

duduclx Posted September 8, 2015 Share Posted September 8, 2015 your GPU and CPU0 are surely not well recognised. please post ioreg and geekbench score first. 1 Link to comment Share on other sites More sharing options...
cyberderf Posted September 9, 2015 Author Share Posted September 9, 2015 Geekbench gives me 4181 for multi-core 32 bits test. Is t normal? http://browser.primatelabs.com/geekbench3/3396358 Here is the ioreg : http://notepad.cc/neehajy49 What do you think? Link to comment Share on other sites More sharing options...
calibre™ Posted September 9, 2015 Share Posted September 9, 2015 Used to have the 8600 and had to disable AppleUpstreamUserClient to fix sluggishness. Its a know issue for 8800 GT/GTS 512 & 8600-8500-9800 series back in the days 1 Link to comment Share on other sites More sharing options...

calibre™ Posted September 10, 2015 Share Posted September 10, 2015 Give it a try nullUpstreamUserClient.zip Link to comment Share on other sites More sharing options...
cyberderf Posted September 11, 2015 Author Share Posted September 11, 2015 So you to be sure.. I remove AppleUpstreamUserClient from the extension folder, put NullUpstreamUserClient, and repair kext permission. And then reboot? Link to comment Share on other sites More sharing options...
jl4c Posted September 11, 2015 Share Posted September 11, 2015 So you to be sure.. I remove AppleUpstreamUserClient from the extension folder, put NullUpstreamUserClient, and repair kext permission.

calibre™ Posted September 11, 2015 Share Posted September 11, 2015 No need to remove AppleUpstreamUserClient. install NullUpstreamUserClient and repair permission then reboot Link to comment Share on other sites More sharing options...
duduclx Posted September 11, 2015 Share Posted September 11, 2015 you should dump and patch ssdt. it will increase cpu power efficience, and so the cpu will work better (increase about 20% the bench score on multi core). maybe your cpu is not well recognised. 4 cpu with 4 thread. you should see: cpu0 = global cpu cpu1 = thread 1 cpu2 = thread 2 cpu3 = thread 3 cpu4 = thread 4 in your ioreg, there is only Cpu 0 to 3. but your ioreg is not readable, so you have to share .ioreg file to be sure of that. ssdt and dsdt may resolve that, and make your system more efficiente. for DSDT (also, see how to patch it to have working other stuff): Paste Patchmatic in /usr/bin folder(finder go/go to...)Open terminal and enter: mkdir ~/Downloads/RehabMancd ~/Downloads/RehabManpatchmatic -extractiasl -da -dl *.aml Close terminal Paste ~/Downloads/RehabMan/dsdt.aml in /EFI/CLOVER/ACPI/patched paste for SSDT: Download ssdtPRgen.sh from piker-alpha.Extract it on your Desktop.Open terminal and enter: sudo mkdir /Extracd ~/Desktop/ssdtPRGenchmod +x ~/ssdtPRGen.sh./ssdtPRGen.sh Answer:y, n, nPaste /Extra/ssdt.aml in /EFI/CLOVER/ACPI/patched Link to comment Share on other sites More sharing options...
