kilven Posted March 23, 2008 Share Posted March 23, 2008 HW: Tyan Tempest i5400xt 2X - e5405 - 2.0 ghz - 1333 FSB .... for a total of 8 cores 4 GB 667 Mhz FBDIMM 8600GT 256 mb Snoop filter enabled. SW: Kalyway 10.5.1 efi boot 10.5.2 Combo update, including the system.kext that comes with it NVinject 0.2.1 Leopard Graphics Update Time Machine and Airport update (provides my current kernel) It thinks I have 8 GB RAM. I don't know if you've seen me whining here (+ other places) before. Though I have been. The graphics lag. I don't mean the 3 minute wait at boot. I mean an intermittent frame rate drop in the graphics. It gets worse with CPU utilization, and worse with lots of memory usage. However it doesn't need either for it to lag. While its hardly tolerable at all, the only showstopper here is the 3d graphics in parallels. They freeze every few seconds...for a few seconds. Totally unusable. Makes me want to ditch OSX86 for windows. But now its story time! So this system is a replacement for an older one. It had a QX6700, 2.6 ghz. 4 cores. It was insufficiently fast. (I do a lot of 3d rendering) So I upgrade/trade to this new system. 8 cores, but each one is only 2 ghz. The graphics are laggy. Can't find a fix. So I tried things. NVinjects, nvinstaller, Natit, Titan, 10.5.2 drivers Various kexts like applesmbios and appleacpiplatform various kernels. efi and non efi mbr and guid idlehalt=0 .. no change cpus=1 .. 1/8 processing power. HORRIBLE snoop filter on/off - no difference New graphics card! The 8600GT is an upgrade from 7300GT. No help! Beamsync. Small but positive difference. Turned off leopard glass dock. Much better dock performance, but still all around system lagginess. which brings me to begging for help and mercy i made a little video demonstrating the lag at its worse. To do this i fully loaded it with large applications open, parallels, 2d rendering, motion graphics rendering, 3d rendering. all at the same time. clearly this is a worst-case scenario and the effect on performance is a bit worse than usual. however even after the little stress test the graphics framerate is dropping. http://www.megaupload.com/?d=341BJD09 it's recorded at 40 fps, but i watched it and you can still see the lag in all its glory. the delayed mouse cursor is a result of screen recording. Only thing i can think of: 2ghz system speed is too slow for all around good performance. Even if it has 8 cores. If you had lag, would you live? I know i can't. any help?

kilven Posted March 25, 2008 Author Share Posted March 25, 2008 What kind of other options for video drivers are possible?... besides various enablers, like nvinject and natit. its an 8600gt and i can't take much more of this stuttery lag. something's not right with it Link to comment https://www.insanelymac.com/forum/topic/95182-laggy-graphics/#findComment-682675 Share on other sites More sharing options...

Then install this package. (after reboot) This should stop the 3 minute wait.

Alex HQuest Posted March 26, 2008 Share Posted March 26, 2008 HW:8600GT 256 mb The graphics lag. I don't mean the 3 minute wait at boot. I mean an intermittent frame rate drop in the graphics. any help? Try to get an officially supported video card. As all 3D operations are managed (mostly) by GPU, getting a supported card may help. Or get a high end video card -- if you are doing that much 3D ops, maybe an 8800GTX or a real workstation graphics card (ie, Quadro or FireGL) can "fix" this.

kilven Posted March 26, 2008 Author Share Posted March 26, 2008 I installed nvidiaefi, no change. Aren't you supposed to remove nvinject first? Well i just did. Now after loading it just sits at a black screen. Not for 3 or so minutes, but as long as you are willing to wait. 15+ and it still hadn't gone. Im going to put nvinject back. What exactly makes a card officially supported on osx86? Link to comment https://www.insanelymac.com/forum/topic/95182-laggy-graphics/#findComment-683624 Share on other sites More sharing options...
kuroishi Posted March 26, 2008 Share Posted March 26, 2008 I also have dreadfully slow graphics. Even the dock magnification is slow. I have a 7900gs in my laptop. I could understand if I were running on 512 of ram but I have 2gb of ram. @_@ Link to comment https://www.insanelymac.com/forum/topic/95182-laggy-graphics/#findComment-683766 Share on other sites More sharing options...
KellyKelly Posted April 6, 2008 Share Posted April 6, 2008 me too as wee as experiencing this problem. But only on Desktop, other 3D application works flawlessly.

nikonnut Posted April 6, 2008 Share Posted April 6, 2008 I believe that someone else had a similar problem and it was cured by switching which port the the DVI cable was plugged into. Just my $.02.

KellyKelly Posted April 6, 2008 Share Posted April 6, 2008 dude that really works! My DVI cable was plugged to the 2nd port. Now I plug back to the first port I notice my it do ran smoother and way faster! THX nikonut! But why is this happen? It is a driver issue? I notice my screen stay blue if i plug back to the second port.

nikonnut Posted April 7, 2008 Share Posted April 7, 2008 I'm not sure why it works or what causes one port to be laggy compared to to the other but I'm glad it worked for you! Cheers!

spanakorizo Posted November 24, 2008 Share Posted November 24, 2008 kilven have u fixed your problem? let's try to help each other here i need to ask u, when u boot the system, it is fast? i also work with 3D programs a lot and if i extremely push it it becomes laggy with no reason after this it needs a restart or logout for full frame rate animations even if i close all apps and i gain some ram, it will stay laggy until reboot/logout i saw your video , i know what u mean if i had the same apps running a lot of time like u i would be the same the last project 90'' edit i did in final cut made me a headache so now back to XP and edit with premiere everyday i boot less in osx because of this and the problem is that it is not clear it needs full load and a lot of testing to start lagging i start to blv it is about the ram or the gfx or whateeeever for me it boots extremely fast (10'') on a velociraptor disk tests are normal and higher for my specs i tried different bios settings, i tried no oc (i'm oc to 3ghz) i bought 150GB veloci just for osx and i had plans to make it raid, it is fast there is no time, it's not fun anymore cause i have projects running and i need fast system not a playground it;s like some times i think to buy a real mac but maybe the lag happens also on real macs? recently i installed osx in a crappy laptop of a friend and man it was more stable (frame rate/UI animation) than the quad core 4Gb ram/ 8800GT i mean..it boot medium perfomance and after a lot of push it was still medium perfomance here we talk about i boot and everything is smoothy,but after hard job leopard slows down Link to comment https://www.insanelymac.com/forum/topic/95182-laggy-graphics/#findComment-976480 Share on other sites More sharing options...
spanakorizo Posted November 24, 2008 Share Posted November 24, 2008 here is a video by the time screen recording apple's motion is playing in the backround i know that this can harm perfomance but so much lag? http://rs483.rapidshare.com/files/167023857/ScreenFlow.mov Link to comment https://www.insanelymac.com/forum/topic/95182-laggy-graphics/#findComment-976530 Share on other sites More sharing options...
