How to restrict the CPU consumption of a specific game.
How to restrict the CPU consumption of a specific game.
Research updates have been made for those who might need to review this. The problem seems linked to outdated video cards introducing a 20ms delay in Vsync, which was likely fixed but wasn’t properly addressed by the developers. Adjusting the timing settings in dxwnd may help, though it could trigger crashes during intense moments like sword fights—especially if delays are too high (e.g., 16ms caused hard crashes after the first enemy). A workaround is to restart the game and play without DXwnd until the issue resolves.
This process is quite time-consuming, but with current hardware (even older HDDs), the game launches quickly.
For reference, I’m playing Robin Hood: Defender of The Crown, a 3D adaptation of the classic title. It’s an older version that faces performance issues due to its reliance on CPU calculations. In particular, the archery section behaves oddly—enemy archers switch to machine gun mode instantly when they start aiming.
My suspicion is that the game’s logic depends heavily on CPU speed. I’ve tried using unstable emulators to slow down the game and temporarily resolved the problem, but I can’t identify the exact tool used.
I’m seeking a solution that requires minimal additional software, especially for AMD CPUs. Any recommendations or alternatives would be appreciated.
My system specs:
- AMD Ryzen 5 3600
- RTX 2070 Super
- DDR4 3000 MHz TeamForce RAM
- 2 TB SSD (500GB NVMe + 500GB SATA + 1000GB SATA)
- Asrock B450M/AC motherboard
- 550B Gamidas Kratos M1 power supply
- 144Hz monitor
It seems highly unlikely that any of these approaches would work effectively or realistically.
If you attempt to control the CPU to reduce the archer's shooting speed, it will also affect defensive actions and choices, making things worse.
You would still be at risk of being shot.
Many games include "beginner" levels where new players can adjust certain game settings to gain time and practice before facing more challenging opponents.
For instance, some air combat games let pilots be slowed down temporarily to help newcomers learn without being overwhelmed.
Consider the options available in Robin Hood—there might be ways to set things up similarly.
These are just my observations on the topic.
This feature enables you to decrease the usage of a specific executable by any desired percentage, allowing it to operate with admin privileges for manipulation of other applications.
Long ago, we would reduce the speed of Taiwanese IBM-compatible knock-off PCs using a tool named "Double-DOS" to make Tetris work.

Once you begin your game, open Task Manager, go to Details, locate the game's EXE file, and adjust its CPU priority.
This won't function unless another CPU-heavy task runs concurrently that utilizes all the cores.
