First of all, forgive me for using translation software to ask questions because I can't speak English. I'm sorry.
Go straight to the theme:
Problem Description: After hanging up, all windows are jammed, or the screen, including random black and fast UI disappearance in the game, is like a memory crash (sometimes half a day, one day, two days, four days, more than a week is rare, sometimes a few hours, half an hour, or a few minutes after hanging up). The hangup window only opens to about 78 viewers. GPUZ display memory and other data are normal task managers to see that CPU memory, display memory and graphics card load are more than half of the remaining space, so it is impossible to have the problem of insufficient hardware configuration. In my other older machine, the number of multiple windows is as low as that of the problem machine, and the same number of hang-up games is as fast as the full load and hang-out for several months. Now this kind of problem!! The difference is that the old machine is the VM10 version of Intel CPU Win7 Physical Machine, the new machine is the latest VM15-15.5 version of AMD CPU Win10 Physical Machine.
Virtual Machine Usage: Open more games and hang up games for old 2-D games (2-D class should not eat any video card memory)
======================================= Problematic new machine information
CPU: AMD3700X 8 Core 16 Threads
Memory: Chi Fantasy Halo 3200 16G*3 = 48G
Hard Disk: Solid 500G
Video Card: Video Chip RTX2060 will be 6G
Physical Machine System: Win10x64 1903
Virtual Machine System: Win7x64 Professional Edition (Original Pure Edition)
VM version: I tried it from VM10-VM15-VM15.5 (VM10 is the direct way to uninstall the display memory when the game runs, increasing the V15-15.5 display memory constantly, normal non-overlapping will uninstall the display memory according to how much the environment around the game loads)
======================================= Problem-free Old Machine Information
CPU: Intel I7-2600K 4 Core 8 Threads
Memory: Kingston 8G*3 = 24G
Hard Disk: Solid 500G
Video Card: Yinchi 660TI 2G
Physical Machine System: Win7x64 Flagship Edition
Virtual Machine System: Win7x64 Professional Edition (Original Pure Edition)
VM version: VM10
=======================================
The virtual machine system of the two machines - configuration - Game - software is all the same in the same number of multiple windows. This problem will occur in the new machine. I have tried to change the software compatibility and hardware compatibility of the virtual machine. The graphics driver that AMD-V has been on has also been upgraded to the latest and reinstalled. Anyway, I can think of it. I have tried or can't find the reason now. I wonder if it's the reason why AMD's new CPU doesn't support VM well, and I can't find the same level U of Intel's to test it now. The most distressing part of this problem is that the time of the problem is completely random and the number of games must be open to hang up. So I have to reload the system/game/software/various configurations every time I test it, and it's been on the verge of collapse for several months. Thank you for your official advice.
Hello, respectful official staff, I'm glad to hear from you patiently. Some of your replies are as follows:
1. I have tried to update Win10 to 1903, VM to the latest version 15.5. As you said, 15.5 may have solved this error. The previous "DX11Shimops: 4962" bullet window did not appear again, but the new and more serious problem came. The crash may occur several hours or a day before. In 15.5 version, game pictures will appear one after another in less than 20 minutes. The difference this time is that instead of "DX11Shimops: 4962" bullet window error, it keeps the card dead, which is the most impressive difference I've made in trying different VM versions.
2. My image card model is: Nvidia RTX 20606G
3. I can't disable 3D acceleration, otherwise the game application can't enter at all. I need to use the 3D acceleration function, otherwise it's meaningless.
4. With regard to error-reporting logs, due to my negligence and ignorance, the system and VM clones have been re-installed many times, which may cause the logs to be overwritten and disappeared. I need to re-simulate such problems, and upload the logs to the FTP server after generating the logs.
=========================
Finally, it is worth mentioning that I have now forcibly installed the win7x64 physical machine on the AMD_3 CPU + X470 motherboard (you know the new product officially no longer supports win7) and then the VM continues to use the old version of V10. Magical things happen. Previous errors have not occurred, windows have not been blocked, has been tested for two days, the first day in the evening when the host automatically restarted. What happened once or again? Maybe I'm not sure why some of the physical drivers are not fully installed or incompatible. I'm not sure that there has been any error or crash since the test was run again. (I'm sure that the current situation is different from any previous attempt, and it feels like it's going to be successful.) But I'll keep watching, and I'll keep feeding back the official results. Thank you very much! 
In any case, I did not install VM tools because it would be blocked by game detection. Of course, after many mistakes, I installed VM tools in WS15.5, but it did not improve. I didn't pay special attention to the VM tools version.
