Delta Force Performances Fix

If you're experiencing FPS drops or stuttering in Delta Force, this guide is here to help. It offers a variety of options and solutions to optimize the game’s performance, including adjustments to graphic settings. With clear steps and practical advice, you’ll be able to get the most out of your gaming experience.

===========

**The suggested adjustments may work differently depending on each user's setup. However, they are risk-free for your hardware and fully reversible. It's important to note that performance issues in Delta Force can also be caused by other factors, such as hardware limitations or other software consuming system resources.**

Add Launch Options in Steam

Note on DX12 Stability

Recent updates have improved the game's stability with DirectX 12. On my hardware, I've observed that while the frame rate (FPS) is slightly lower by about 2–3 FPS compared to DirectX 11, the overall gameplay is smoother and more stable, with fewer fluctuations (resulting in a more stable 1% low).

If you're using DX12 (default mode when no -dx11 command is added), the -useallavailablecores command may not be necessary. However, testing both configurations—with and without this command—is recommended. Depending on your setup, you might find that one option provides better stability or performance. Stick to the configuration that works best for your needs.

How to Set Launch Options in Steam
Navigate to your Library in Steam and locate Delta Force.

1. Navigate to your Library in Steam and locate **Delta Force**.
2. Right-click on the game and select **Properties**.
3. Under the **General** tab, find the **Launch Options** field.
4. Enter the following:

-dx11 -useallavailablecores


Additional Note: The -high Command

If you'd like to prioritize the game in your system’s task manager, you can add the -high command to the launch options. This might help reduce stuttering and improve performance by allocating more CPU resources to the game. However, keep in mind it can impact other applications running in the background, which might lead to slower performance for those programs. Use it based on your needs and system setup.

this will looks like this:

-dx11 -useallavailablecores -high

Disable AA via Engine.ini

If you notice any unwanted changes, simply remove the line from the configuration file.

Here’s how to disable it:

1. Right-click **Delta Force** and select **Properties**.
2. Go to the **Installed Files** tab and click **Browse**.
3. Navigate to the following folder:

C:\Program Files (x86)\Steam\steamapps\common\Delta Force\Game\DeltaForce\Saved\Config\WindowsClient

4. Open the `Engine.ini` file with a text editor (e.g., Notepad).
5. Add the following lines at the end of the file:

[/script/engine.renderersettings]
r.PostProcessAAQuality=0
r.Tonemapper.Quality=0

(if the first line not work for you you can use the next one )

[SystemSettings]
r.PostProcessAAQuality=0
r.Tonemapper.Quality=0

"Maybe you must set the file to read only for working"
Howto:
Right click on "Engine.ini" then check the "Read Only" and press "Apply"

6. Save and close the file.

Fix Mouse Issues

If you notice mouse smoothing or acceleration issues, follow these steps:

1. Right-click **Delta Force** and select **Properties**.
2. Go to the **Installed Files** tab and click **Browse**.
3. Navigate to the following folder:

C:\Program Files (x86)\Steam\steamapps\common\Delta Force\Game\DeltaForce\Saved\Config\WindowsClient

4. Open the `Input.ini` file using Notepad.
5. Add the following lines after the first line ("[/script/engine.inputsettings]"):

RawMouseInputEnabled=Enabled
bEnableMouseSmoothing=False
bViewAccelerationEnabled=False
bUseMouseForTouch=True

6. Save and close the file.

Graphic Settings advice

If you're looking to fine-tune your graphics settings and aren't sure what to adjust, here’s what I optimize on my setup. You can use these settings as a base and tweak them to suit your needs for smoother gameplay and better enemy visibility.


You will find here the settings i just tunned the other things is by default for me.

Display Settings:

• Display Mode: Fullscreen ( less imput lag and better FPS in full screen )
  
• 
  
• Resolution: Native (e.g., 3840x2160)
  
• 
  
• Refresh Rate: Max your monitor supports (e.g., 165Hz)
  
• 
  
• V-Sync: Off
  
• 
  
• Field of View (FOV): 110–120
  
• 
  
• Motion Blur: Off
  
• 
  
• Weapon Motion Blur: Off
  
• 
  
• Depth of Field: Off
  
• 
  
• Sharpening: 65–70%

Graphics Settings (Custom Preset):

• Graphics Style: Default
  
• 
  
• Reflections: Low ( broken there no diff on ultra or low )
  
• 
  
• Ambient Occlusion: off ( it add shadows on the objects, the only valable options is off or Ultra, for me i put if off so i can see better, ppl hiding in shadows )
  
• 
  
• Texture Filtering: High ( i leave high for me, but impact is minimal if you have less Vram you can go to low or medium )
  
• 
  
• Particles: High( Low for best performance, this option is high impact on FPS, for me i use High average impac between low and high is actually arround 10 FPS )
  
• 
  
• Distortion: Low
  
• 
  
• Scene Detail: High ( High or better Ultra )
  
• 
  
• Scene View Distance: High ( For snipers go high for the other stay at low )
  
• 
  
• Textures: High (or Medium if VRAM-limited) Actually for me i have nothiced zero diff between high and ultimate so it stay on high.
  
• 
  
• Streaming: Ultimate ( On Ultimate, all textures are fully displayed with maximum detail. Dropping to Ultra slightly reduces texture quality. Below Ultra, some textures completely disappear (like fences, paintings, or cracks), and the lower the setting, the more visual details vanish. The difference in VRAM usage between Low and Ultimate is approx ~1GB, with a performance impact of about -1 to -2 FPS on my setup.)
  
• 
  
• Global Illumination: Low
  
• 
  
• Shaders: High
  
• 
  
• Shadows: Low
  
• 
  
• Shadow Map: Low
  
• 
  
• Post Processing: Low
  
• 
  
• Volumetric Fog: High ( if you want add some fog or dust stay on high or if you don't want it go low )
  
• 
  
• Animation Quality: Medium ( well here same thing, i don't know why they added this option, for me it change nothing you can go low or like me on medium ^^ )

DLSS = Quality

Skip the Intro Videos

If you want to skip the intro videos, follow these steps:

1. Locate **Delta Force**, right-click, and select **Manage** > **Browse Local Files**.
2. Navigate to this folder path:

C:\Program Files (x86)\Steam\steamapps\common\Delta Force\Game\DeltaForce\Content\Movies_HD

3. Delete these three files:

V_logo_HD.bin
V_logo2_HD.bin
V_logo2_looping_HD.bin

Done! The intro videos will no longer play.

Optimizing Your Energy Plan for Maximum Performance

If you want to optimize your PC's energy settings for better performance (for desktop only cuz if you use laptop it impact your battery), follow these steps:

Open Command Prompt as Administrator:

• Press Windows + R to open the Run dialog.
  
• Type cmd in the box.
  
• Hold down Shift + Ctrl and press Enter to run Command Prompt as an administrator.

Enable the Ultimate Performance Plan:

In the Command Prompt window, type the following command and press Enter:

powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61

Activate the Plan:

• Go to your Energy Settings (Control Panel > Power Options).
  
• Select the Ultimate Performance plan for optimal performance.

This configuration ensures your PC operates at its maximum potential.

Prevent the settings from resetting at each boot ( troubleshooting)

If you experience abnormal game behavior where the settings are reset to default every time the game is launched.

In this case, you should check your software that manages your GPU, either Nvidia app or AMD Catalyst, because depending on the settings you have chosen or not chosen ^^, the software may optimize games for you, and not always in a good way. Once the automatic optimization is disabled, your problem should be resolved.

The ultimate alternative is to set the game files to read-only, but that being said, I’m not sure their anti-cheat system will appreciate that.

Added graphics settings tuning for ppl who need it

[Scax]

Take a look on the launch options i have made a small update

[Scax]

@ButtButt, the card model doesn't matter here you can have 3090 or 3080 or like me 4070ti. There no risk to test these setting so try and see by yourself if it help

[ButtButt]

I've been experiencing a buncha weird shit lately, sometimes I can move in operation games but I cant run or use other operators' skills, or my guns not out or i'm stuck in the loading screen at 95% and I know it's not my pc cuz i'm rocking a 9900X, I used your launch configs, and a 3080 12gb, thoughts?

为什么steam s4赛季不让购买通行证？说什么交易风险联系客服处理？不在wegame上玩就不让充钱是吧

[Zdrv]

It's strange, but I have less fps with DX 11 than with 12

[Scax]

@Ixillia well with your spec it would be better to stay with dx11 on and all cores :)

[Ixillia]

oh? the stutter and fps drop is because the game itself using dx12? i thought at first it's because of my laptop spec: ryzen 5 5600H and rtx 3050 4gb (95 watt) with 16 ram.

so that's why i experienced random fps drop and stutter either in warfare or operation mode. i guess i'm trying the dx11 launch option later.

[Scax]

Yep i have tested to get back to dx12 few day ago and i can confirm still total crap so i suggest to stay on dx11 and all cores on.

This game ran butter smooth on my RX 580 8GB and Ryzen 1700 in DX11 with the "use all cores" launch options, while DX12 was just lower performing.
After upgrading to a RX 6700 10GB and a Ryzen 5800X, it's buttery smooth with the same exact install and launch options..
I tried removing the -dx11 command, and it was a trainwreck during intense firefights with explosions going off.. It wasn't shader compilation stutter, either.
It remained a stuttery mess during intense scenes until I switched it back to DX11.
