Rtx 3090 slow in opencl

[Sontungmtp]

I dont know why my card is normal when gaming but when test opencl in realbench, its very slow. It has only 4000 ksamples/s and it was 94000 before. I tried to run blender after weird perf in realbench happens . Bmw test in blender was 1.8s before but now it took forever to run with cuda or optix. What is going on?
