Increase Mac Gaming Performance
When gaming, fans are at a full blast of 5400rpm and package temps are constantly at 60°C. After forcing macs fan control to set a constant fan speed of 4000rpm to the SMC on Mac OS, package temps are now at a constant 78°C when gaming on bootcamp. Now that sounds about right. Plus there's no loss in performance. Optimize Virtual Machine Performance for Mac OS X Applications or Windows Programs. You can choose one of the following options from the Performance menu: Faster virtual machine: More of your Mac resources will be dedicated to Windows. The performance of Windows programs may be increased significantly, but there will be less resources available.

There are a number of things you can do to boost your gaming PC without resorting to spending lots of money on hardware. From updating graphics card drivers and tweaking their settings to disabling autorun applications, each one will have an effect on the performance of the games you play. Question: Q: Poor gaming performance in Boot Camp I recently purchased the base model iMac Pro which includes Radeon Vega 56 GPU. I am running Windows 10 in Boot Camp with the latest updates and have installed the latest drivers from Apple, but the performance when trying to play games in Boot Camp is pretty poor.

Need a better performing virtual machine? Do you work on the Windows side more often than on the Mac? Let me guide you through a few built-in settings in Parallels Desktop that will have a positive impact on your VM performance.
Using Optimizationsettings, you can: Why is gaming bad on mac.
- Balance the resources between either Mac OS X applications or Windows programs
- Tune Windows for better performance or add more graphical features
- Optimize your computer for better battery life or higher performance
- Conserve disk space
To access Optimizationsettings, Option-click (Alt-click) the Parallels icon in the upper right menu bar, select Configureand go toOptions→Optimization. Alternatively, you can use any of the methods outlined in this KB article.
Now let me go through each optimization option in more detail.
Optimize Virtual Machine Performance for Mac OS X Applications or Windows Programs
You can choose one of the following options from the Performancemenu:

- Faster virtual machine: More of your Mac resources will be dedicated to Windows. The performance of Windows programs may be increased significantly, but there will be less resources available for the Mac applications.
- Faster Mac: More of your Mac resources will be dedicated to Mac OS X. The performance of Mac OS X applications (while you run your VM) may increase and Windows programs may slow down.
To set Parallels Desktop to automatically optimize performance for Mac OS X or Windows depending on which application or program you’re working with at the moment, you can Enable Adaptive Hypervisor. When you’re using a Windows program, more resources are given to Windows, and when you’re using a Mac OS X application, more resources are given to Mac OS X. Sounds pretty straightforward, right?
Tune Windows for Better Performance
For this feature, all you need to do is to select the Tune Windows for speedoption.
Some Windows features that tend to slow down performance, such as animations during startup, will be disabled.
Optimize Your MacBook for Longer Battery Life or Higher Performance
The Powermenu contains the power and performance related options:
- Longer battery life. If you have a portable Mac that you often use unplugged, you can choose this option to lower down power consumption. This may slightly reduce Windows performance.
- Better performance: This option (selected by default) maximizes Windows performance, but uses more power.
Automatically Conserve Disk Space
In most cases, the space that Windows takes up on your hard disk expands as you add files and other data. But what happens when you remove data? Select Real time virtual disk optimization to set Parallels Desktop to automatically reduce disk space as you delete files.
Congratulations! You’ve just optimized your VM!

I recently purchased the base model iMac Pro which includes Radeon Vega 56 GPU. I am running Windows 10 in Boot Camp with the latest updates and have installed the latest drivers from Apple, but the performance when trying to play games in Boot Camp is pretty poor. For example, when playing Overwatch, I can't even maintain 30 FPS regardless of the settings I choose. Reading other non-Apple forums, it seems others are running into similar issues. It seems the drivers just haven't been optimized yet. Anyone else experiencing the same?
