8.1 Changes, can no longer maintain 5 Windows

[Rocknard]

I would agree as I try DX12 where I physically set it, and it's much worse.

Now that only leaves out, what else could be causing my screens to just Disappear I believe it's due to the CPU but what is not causing my Huge increase in CPU if I have confirmed to not be taking advantage of any of the new graphic changes if I am not running DX12

Hello everyone, I'm having the same issue (window closing), checked and all are still in DX11 and I have really no performance issues, just the 2nd window that always closes.

Anyone has any solution for this?

Thank you.

I got a clip of my second window closing, it's random on what window closes I imagine if I pinpointed which CPU is running which PID I could find out more

DX12 should free up CPU resources, but otherwise it eats up more from the GPU VRAM.

Clearly that's a crash of the game client due to, what looks to be, the hardware being overloaded, and any crash logs are going to be stored in the /Logs/ folder.

Also, those slave screens look pretty smooth - Are you running them at a high framerate? In addition, sound playing from all windows at the same time is going to increase the load too. Lowering your background framerate and disabling background sound are two easy ways to reduce load.


Finally, what people who are experiencing issues can try is:

• nVidia users can try rolling back their driver to 417.01 or just a little prior to that (although a brand new driver just came out today).
• Disabling the new multi-threading improvements with the following command: /console gxMTDisable 1 However, if that doesn't fix anything, then you should probably re-enable those enhancements by re-entering the command and switching the 1 to a 0.

I don't know if this will help anyone, but here is my test.

5 WoW open sitting at the mission table not moving. Latest version of nVidia driver 417.35 Main on 7 slaves on 1. Using the performance monitor built into windows task manager.

DX11: CPU 55%, Mem 43%, GPU 56%
DX12: CPU 45%, Mem 38%, GPU 55%

DX11: CPU 55%, Mem 43%, GPU 56%
DX12: CPU 45%, Mem 38%, GPU 55%

While these numbers give somewhat of a picture to you for your system, they, on their own, don't really say much for others because when it comes down to percentages, they're different for every single user depending on their hardware.

For example:

• with CPUs, 50% CPU of a 16-core chip is going to be eight cores, a 10-core chip is going to be five cores, and an 8-core chip is going to be four cores (this doesn't take into effect CPU generation, IPC, overclocks, etc.)
• with RAM (or VRAM), if you have 64GB then 50% is 32GB, but if you only have 32GB, then 50% is 16GB
• with GPUs, 50% overall usage of a GTX 1060 is going to be much when measured on a GTX 2080 Ti because the newer GPU is more powerful and can do more with less effort

In terms of measuring performance, having actual numbers along with hardware specifications is going to help people more accurately establish how their setup aligns with yours. However, in Rocknard's case, an AMD FX-9370 was released in July of 2013, so it's going to be incredibly difficult to compare your setup to theirs, unless you: A) have similar hardware (unlikely), or B) want to go back through the several generations of benchmarks/reviews trying to figure out how the two CPUs might compare today in terms of overall horsepower, because most (if not, all) review sites aren't going back 5+ years to see how those chips perform in today's workloads.

I will try disabling the improvements and see, in regards to my slaves no they run at 30 fps in background 60 on my main.

Hi Rocknard. I have a similar issue since 8.1. Before yesterday I could easily run 5 toons. Last night I saw that my main memory is full when I have 5 wow clients running. Each wow.exe takes 3GB and I only have 16GB total, so Windows starts swapping to the temporary pagefile and everything slows to a crawl.

I looked through your screenshots but I didn't see anything about your PC's memory. Did you look at Task Manager while running your 5-box?

I'm pretty sure your issue stems directly from the fact that you upgraded from 1920x1080 to 3840x2160, which is a 300% increase in pixel count and requires a lot more resources to run.
