On my windows 7 OS-es it gives sms this :
ERR: ADL API function: ADL_Display_PossibleMode_WinXP_Get is missing.
{"gpus": [{"load": 91, "temperature": 69.0, "name": "ATI Radeon HD 5700 Series", "level": 2, "adapter": 0, "mVoltL2": 1200, "memL2": 300, "active": 1, "memL0": 300, "memL1": 1200, "id": 152824734, "mVoltL1": 1200, "fanSpeed": -2, "mVoltL0": 1200, "coreL2": 930, "coreL1": 850, "coreL0": 157}], "nGpus": 1, "time": 1313075760.3099999}
But I need pure output without extra lines.
I think this error text is omitted from the most recent version of ClockTweak. I recall that after updating to v0.91b, the error is no longer rendered.
