Hello, I was using ATI Tool for OCing my X1900XT for some time now, without problems. I made two profiles : One profile for 2D mode (GPU @ 500MHz @ 1.15v and MEM @ 500MHz @ 1.9v) and one for 3D mode (GPU @ 730MHz @ 1.5v and meme @ 864MHz @ 2.15v) and use the 3D Detection feature to swap automaticaly between this two profile when a 3D application is detected by ATI Tool. Work fine till yesterday. I received some days ago a Logitech G15 keyboard, with a LCD screen on it. To make it fun, i make some cool setups to display on : cputemp, cpu load etc.. and GPU temp and FRAPS. LCD Studio got a ATITool plugin and a FRAPS Plugin. I originally want to swap to the FRAPS layout when a 3D app is detected by ATITOOL...and found this bug : When lcdstudio is launch with the ATITool plugin, AtiTool is not able anymore to detect 3D Mode. When LCDstudio not started : i can use Atitool with 3D detection again. Don't know if it's a problem with the plugin of Lcdstudio or not (but i guess so)... I'll post a copy of this thread on the LCDStudio forum. Using last LcdStudio, and ATITOOL beta 14.
