guitarsniffer is overly CPU intensive.

[MarcG2]

When I have guitar sniffer running in the background, it completely maxes out one of my CPU cores and ends up using about 20% of my i7-8750H. Is there a reason the program needs to run unrestrained?

Hello,
Same for me, 50% cpu average on laptop. So I can't play because it slow game to 20fps average.
I assume that 4 cpu cores is enough.

I hope to see quicky a fix.
Thanks for all

Hi guys,

I believe the issue is that I'm polling the device too many times for your CPUs.

My CPU is a Ryzen 7 1700 so I only see minor CPU usage on my end - likely because it's so much more powerful.

@MarcG2, @Osin, and anyone else that has this issue, could you please follow the below steps to get your DxDiag.txt and attach it to your comment?

Hopefully, if I can limit my CPU to have the same performance as yours, I can try and improve performance.

Getting DxDiag.txt

1. WIN+R
   

2. Type dxdiag & Click OK
   

3. Click Save All Information
   

4. Save it in a place you know
   

5. Navigate to that directory
   

6. Drag it on to your comment
   DxDiag.txt

Here is my system info. What is the utility set to poll at currently? It seems like it's set poll as fast as possible.

@MarcG2 so the offending function is this one, the issue is that I have no delay currently between reads, so it'll just keep reading as fast as possible until the sniffer is told to stop.

Personally I didn't see any huge performance hits from this, but it's quite obvious it must be terrible performance wise if you're seeing massive issues with it.

I'll try and add some delays in when I get some time; hopefully, by emulating your environment, it'll make it easier to spot the issues 👍

@artman41 I have Intel CPU's in my laptop and desktop I can test with. I noticed it was reading a high percentage, but I was never unable to play the game. But I can definitely help you look into it

Was this issue ever addressed? It looks like the dev hasn't this updated this project since I first posted this.

Edit: Never mind. It looks like this version is now the recommended utility for RB4 controllers.

@MarcG2 that is perfect because artman has been MIA on this, and I never found more time to look into more and update it further. I also haven't found my wireless adapter since I moved to a new house, so I haven't even been able to test anything lately!

I was trying out the other utility and it the controller seemed much less responsive than it should be. I'm not sure why, I'll need to test it more. If you get the chance to try it out, let me know

@MarcG2 sorry this is months later, just going through some old issues to get things updated. I got the latest version of that other tool installed and had no issues with guitar! Haven't tested with drums yet. I'm now recommending that tool be used since it's recommended by the Clone Hero team and is currently receiving updates.
