What absolute rubbish.
Couldn’t let that pass unchallenged. Anyway, like others, I strongly suspect that the issue isn’t 7.5.1. I had some problems recently and it was a slow problem tracking it down using LatencyMon and DPC Latency checker. It took several hours but in my case I isolated it to the Blu Ray drive, which was quietly going nuts in the background. Unbelievably (and this really is unbelievable, I would never have believed it if it hadn’t happened to me), merely putting a disc in made all the problems vanish completely.
Funny things, computers.
Windows computers.
Using 7.5.1 and 23gb of template on VE Pro 4 I was on 1024, now its a very very comfortable 256 (7ms in each direction) - I could easily go lower, but that latency is easily good enough for me and I’d rather have it running with plenty of horsepower to spare.
