Guía en Español

In my personal opinion, I think NeoBards Entertainment did an excellent job optimizing the game on PC. Even so, it’s important to keep in mind that this game isn’t designed for very modest computers, and even in some more recent ones it presents stuttering.

The method is identical to any other Unreal Engine 5 game, so you shouldn’t run into major issues when following this guide.

Ultimate Engine Tweaks[www.nexusmods.com]

Credits to P40L0X[next.nexusmods.com] for taking the time to optimize this engine in almost every game that uses it.

Depending on your setup, your performance could be negatively affected. You can try alternatives like:

or

Both mods use less aggressive CVARs compared to Ultimate Engine Tweaks. It may be useful in some cases.

Installing the .ini file is simple:
Just copy the file in

To access the location without changing any Windows settings, simply press Windows + R and run the following command:




For some strange reason, the opening cutscene (even in NG+) will display a black screen when using any of the optimization mods with Frame Generation. Temporarily removing FG fixes the issue.

The good ending also has this problem.

The UFO ending will not work correctly when using Frame Generation by modifying Engine.ini.

Some cutscenes (again, even in NG+) may freeze when using SHfFix.

We're interested in performance without significantly sacrificing visual quality—and that's exactly what we're going to achieve.
All we need to do is download the .ini file (VRR or No VRR, your choice) from Nexus Mods and tweak a few settings to make it as optimized as possible.

First, uncheck the Read-only option and open the .ini file, then add the following line at the end, without the comments explaining what each one does:



Once you add the line that disables virtual shadows, you must change one to avoid glitches in shadows


Set the file to read-only again.

Warning: Depending on your setup, performance may be worse after disabling virtual shadows, so try it and draw your own conclusions.
Sometimes it's better to have them turned on.


You can also try adding more experimental parameters that I haven’t tested, so I cannot guarantee better performance:



I don’t recommend disabling Virtual Shadow in Optimax - Performance, since the cascade shadow distance is reduced so that virtual shadows handle all the work and avoid double processing. Disabling it will only leave very poor shadows in both distance and quality.









0 equals Low and 3 equals Epic in Unreal Engine 5.
I recommend testing values from 0 to 3 for each advanced setting and seeing which one best fits your needs.

DLSS Frame Generation libraries are not natively available; however, you can choose to use FSR Frame Generation until Konami implements it in a future update:


It may present some visual problems, due to the Frame Generation not being correctly implemented.

Some of these problems can be fixed by using OptiScaler. More info below.

Updating DLSS to the latest version is always the most optimal choice, especially in poorly optimized games or those with Frame Generation, since this technology is tied to DLSS on NVIDIA, as well as FSR for AMD.

We can use an easy method: download DLSS Swapper[github.com] and run it.

Once inside the application, it will load all the games in your library. What we’re interested in is updating SILENT HILL f.


You just need to update the DLSS and FSR libraries, although for now it’s better to do it manually since the latest recent update is not yet available in the tool.


DLSS 310.4.0[www.techpowerup.com]

FSR 3.1.5/4.0.2[gpuopen.com]

If you have a low end setup, you can try forcing DirectX 11.

In the game’s Steam properties, enter the following parameter:


-dx11

The only downside of this method is that Frame Generation via FSR—and probably all upscaling technologies—may not work properly under this architecture.

I recommend it as a last resort, since it can provide much higher performance and stability at the cost of a slight graphical downgrade and some funny glitches like the following one.





You can use it alongside OptiFG or by spoofing DLSS with OptiScaler. More info below.

Some users, myself included, may experience issues when using the default Frame Generation in Unreal Engine 5 due to its poor or nonexistent implementation in the game’s code. Among these problems, one of the most noticeable is that subtitles flicker during cutscenes.

This method is simple: just download the latest test build of OptiScaler from the official Discord server[discord.gg] and install it according to your preferences.

Very important: if your graphics card is AMD or Intel, avoid enabling the spoof option as it may cause visual glitches in global illumination in Unreal Engine 5, especially in games with fog like this one.
I recommend enabling spoof only if you want to use emulated DLSS or use Frame Generation in DirectX11.


Detailed instructions coming soon—you’ll know OptiScaler is correctly installed if you see the following splash in the bottom corner of your screen.



Once OptiScaler is running, make sure to select FSR 3.X in Upscaler and FSR 3.1.5 in FFX Settings (Or DLSS if you have an NVIDIA GPU).
Save the changes and, once you restart, select FSR 3.1 FG in Frame Generation and FG Source. (Again, you can choose DLSS if you want better quality on an NVIDIA GPU)

Save the changes again and select Active and Allow Async in the Frame Generation section.



Finally, save the changes and you’re done. Some of the most noticeable problems caused by frame generation will be resolved, though there are still a few left that we hope Konami will officially fix soon.




If you're experiencing crashes or issues related to FSR's Frame Generation and the above method doesn't fix the issues, you can choose OptiFG (Upscaler) and select HUDFIX in the scaler's advanced options.



The only issue with this method is that it can freeze the game when alt tabbing.

I recommend changing the display mode from full screen to borderless window in the game options. Alt tabbing issue can be fixed by forcing NVIDIA Reflex/AMD AntiLag 2.

Since NVIDIA Reflex isn't present in the game files at the moment, it can't be forced, even with OptiScaler. We'll just have to wait for a future update that will add native Frame Generation + Reflex and the ability to use forced AntiLag 2 thanks to OptiScaler.




Change the value to 'false' and save the file.

— Unlocks the default 30 FPS cap in cutscenes and adds some much-appreciated quality-of-life improvements, such as providing a fix for Ultrawide screens and skipping the long Konami intro.

While the native performance of this game is far better than previous Konami titles like Silent Hill 2 or Metal Gear Solid Delta, there’s always room for improvement to make better use of the hardware thanks to the modding community.

This guide will be updated in the coming days to add more methods for enabling Frame Generation and to update additional libraries that can improve overall performance.

That’s all for now—I hope this guide has been helpful.
