Open CL texture decoder not working anymore

You are definitely running into low power mode, a gtx 770 to drop performance at 2x is ridiculous (i have a 560 ti and it doesn't drop performance going to 2x, in most games even in 3x). Go to nvidia panel and set at the global settings your gpu to maximum performance, it should have the same result as enabling OPENCL. All in all the option doesn't speed up anything, it only wakes up your gpu from low power mode if you have an extremely fast new gpu (that doesn't happen with older gpu's such as mine).
