The Nvidia Control Panel offers control over the driver’s graphics settings and various other features. If you have an NVidia GPU in your PC build or gaming laptop and play Hearts of Iron IV, then you need to have the best NVidia Control Panel graphics settings for Hearts of Iron IV.
If you don’t optimize your NVidia Control Panel settings, you miss out on FPS improvements, graphics quality improvements, and lower latency in Hearts of Iron IV.
When you first install the Nvidia Control Panel on your computer(Or it gets installed automatically by Windows updates), all graphics settings are already preconfigured by Nvidia. But that doesn’t mean that they are the best for your system.
Don’t worry; in this post, I will go in-depth on how to properly configure and optimize your Nvidia Control Panel settings to achieve the maximum performance possible, boost your FPS, have less input lag, and fix shuttering, flickering, and fps drops in Hearts of Iron IV.
Before you optimize the Nvidia Control panel settings for Hearts of Iron IV, I highly recommend uninstalling any previous drivers and downloading and installing the right Nvidia driver for Hearts of Iron IV on your computer. If you are unsure which driver you should get, you can check out my list of the best NVidia drivers for each game, including Hearts of Iron IV.
Best NVidia Control Panel Settings for Hearts of Iron IV
Assuming you installed the best NVidia driver for Hearts of Iron IV, you can go to your Desktop, Right-click, and then select “NVidia Control Panel” to open up the panel itself, where you can adjust all the NVidia settings.
Best NVidia Control Panel 3D Settings for Hearts of Iron IV
Click on the “Use the advanced 3D image settings” option, and click Apply.
Then move to “Manage 3D settings” tab. Below I will go through all the settings one by one.
Image Scaling replaced the old option called Image Sharpening. Image Scaling will downscale the resolution and then sharpen the image in Hearts of Iron IV. It reminds me of DLSS, but it’s not even close. Just keep it disabled.
Keep it off on the NVidia Control Panel, and if you want to enable it, do it through the Hearts of Iron IV settings. It makes the shadows look a little better, but it’s not worth it.
Turn it off here and enable it in Hearts of Iron IV if needed. It makes everything sharper, more precise and looks better.
If you enable it on the NVidia Control Panel and start noticing weird graphics in Hearts of Iron IV, come back to the NVidia settings and disable it.
Antialiasing – FXAA
“Budget” less FPS taxing anti-aliasing option. Keep it off.
Antialiasing – Gamma correction
Almost every modern game, including Hearts of Iron IV has Gamma Correction already enabled. Useless setting; keep it off.
Antialiasing – Mode
As I said above, keep it OFF and enable it in Hearts of Iron IV if you want it ON.
Antialiasing – Setting
Antialiasing – Transparency
Doe’s nothing in Hearts of Iron IV, so keep it off.
Background Application Max Frame Rate
If you are in a game and you alt+tab out Hearts of Iron IV, then having this setting set will cap the FPS when you tab out. But it only works for Windowed mode or Borderless. If you are playing on full-screen, this setting will not work.
CUDA – GPUs
If you have only one GPU, you can skip this setting. If you have multiple GPUs, select the most powerful one because if you run a GPU-accelerated application that uses CUDA, it will come and use that specific one.
DSR – Factors
Dynamic Super Resolution(DSR) should be set to OFF unless you know what you are doing.
DSR – Smoothness
Low Latency Mode
Turn it OFF in the NVidia Control Panel and turn it ON in Hearts of Iron IV.
Recommendation: High-Medium systems, turn OFF. For low-end systems, try ON / Ultra and see which one works best.
Max Frame Rate
There are many more efficient ways to cap your maximum frame rate, so there is no reason to use this one. In most modern games, including Hearts of Iron IV, you can cap your FPS via Hearts of Iron IV’s settings.
Preferred Refresh Rate
Recommendation: Highest available for the smoothest experience in Hearts of Iron IV.
Multi-Frame Sampled AA (MFAA)
OpenGL rendering GPU
Recommendation: Choose your NVIDIA GPU
Power management mode
Recommendation: Prefer maximum performance
Shader Cache Size
Recommendation: Driver Default
Texture filtering – Anisotropic sample optimization
Texture filtering – Negative LOD bias
Texture filtering – Quality
Recommendation: High performance
Texture filtering – Trilinear optimization
Virtual Reality pre-rendered frames
