A week ago I have installed Gigabyte GTX 560 Ti OC on my computer. It was working fine from that day. However today I sentenced slight variation in my computerís graphics performance and for that reason I went to check the latency. For this I have used DPC latency checker. While checking I got that the latency is too high which is above 4000 points. I know it is not normal and I didnít find any way to fix this thing. I am also using Gigabyte EP45-UD3L most up-to-date bios. It seems to me like driver issue but I am not sure about it. Can anybody help me?
