If you look in the Hardware Software forum, you will see a fairly new thread titled "Processes". I encourage you to go there after reading through this one (I'll keep it short).
In a discussion with Skuzzy, I discovered that NO ONE has been complaining about micro-freezes or stutters (using ver Dx9). Having seen many folks talking about it on Vox 200, I disagreed. Then I realized that talking about it on Vox 200 isn't really making the HTC folks aware of issues that we may be having...so +1 to Skuzzy (If you are seeing issues, please write them up).
In follow-on discussions, Skuzzy suggested that I check the number of processes that my computer is running (citing that Windows 7 shouldn't be running more than around 40 processes). My system was running 97 processes. Skuzzy suggested that I go process by process through the list and turn off the ones that are not required in an effort to figure out what is causing the stutters/micro-freezes. He also offered that I could Google each one to figure out if it was critical.
Now, Rodent57 doing things inside a computer
is roughly as good a plan as a pig looking at a wrist watch...but I gave it my best. Here is what I've learned:
1) If you have other games (IE: ORIGIN for Battlefield1, or WOW) running, you can kill them with no degradation to your system. There are LOTS of other processes running in there that you can also shut down to test. Of course, you'll have to restart you system to get them back up (which is a two-edged pain), but may help you discover what the source of your Mini-freezes is/are.
2) If you have multiple sound cards in your system, you should probably turn off the one(s) that you are not using....Skuzzy says there are known issues/conflicts between the drivers of the major manufactures (My paraphrasing of his words). I shut down my NVIDIA High Def Audio sound card (It was only supposed to be driving my TV Speakers...which I DONT use) --- I found it in: Control Panel, System, Device Manger, Sound, Video, Game controllers.
The goal of the exercise is to see if you can get your CPU usage % down to 0% (with an occasional momentary bump to 1%). I turned of 30 processes, and got to the goal of 0% CPU (with momentary bump to 1%).
Then I turn on Ventrillo and the system used 4%...sigh.
SO, the GOAL of this very non-technical write-up is to encourage anyone that is experiencing the Micro-Freezes to:
1) Write it up for HTC to be aware (Make sure you tell them if you are using DX9, or Dx11). We can't really expect things to get better if they don't know we are having issues.
2) Offer a possible fix to your issue.
Lastly, there are some more technical suggestions in the Hardware/Software "Processes" thread that is also running right now.
