My Summer Car: Best pro_preferences.xml for FPS Fix

The primary goal for My Summer Car performance optimization is Draw-Call Reduction and Lighting Culling. The game’s default “Golden Eye” or “Shitty” presets still leave high-cost shadows and reflections active in the background. This configuration manually zeros out the most taxing visual layers, focusing purely on keeping your FPS stable while driving the Satsuma at high speeds.

File Location

The preferences file is found in your local AppData folder. Ensure you are not in-game when editing:

%LocalAppData%Low\Amistech\My Summer Car\pro_preferences.xml

Technical Configuration (The 2026 “Smooth-Ride” Template)

Open the file with Notepad. Update the following XML attributes to these specific values for the best balance of visibility and performance.

<?xml version="1.0" encoding="utf-8"?>
<PlayerPreferences>
  <GraphicsDetail>1</GraphicsDetail>
  <Shadows>false</Shadows>
  <DrawDistance>1200</DrawDistance>
  <Reflections>false</Reflections>
  <SunShafts>false</SunShafts>
  <Bloom>false</Bloom>
  <AntiAliasing>0</AntiAliasing>
  <MirrorQuality>0</MirrorQuality>
  <WaterQuality>0</WaterQuality>
  <Skidmarks>false</Skidmarks>
</PlayerPreferences>

Parameter Breakdown:

• Shadows=false: This is the single biggest FPS boost. My Summer Car’s shadows are calculated in real-time for every leaf and part; disabling them can increase FPS by 30-50%.
• DrawDistance=1200: The default can go up to 6000+. Since you rarely need to see the entire lake while driving, 1200-1500 is the sweet spot to prevent the CPU from loading distant terrain.
• MirrorQuality=0: Mirrors in MSC are actually secondary cameras. Setting this to 0 disables the real-time render, which is essential for low-end PCs, though you will have to drive using the exterior view or sound.
• Reflections=false: Removes the dynamic reflections on the car’s paint and windows, significantly reducing GPU frame-time spikes.

Strategy for 2026 Performance Stability

• The “MOP” (Modern Optimization Plugin) Rule: In 2026, you should not play MSC without MOP or Reharmonization. These mods disable objects that are not in your field of view. Using pro_preferences.xml tweaks alongside MOP is the only way to reach 60+ FPS in the town area.
• Clear the Trash: Every loose beer bottle, spark plug box, and sausage wrapper in the world is a physics object. If your FPS is dropping over time, use the MSC Editor to “Teleport All Loose Items” to a single location or delete them.
• Resolution Scaling: If you are on a 4K monitor, the Unity engine will struggle. Set your resolution to 1080p and use Integer Scaling in your GPU settings for a sharp look with much higher performance.
• Launch Options: Right-click the game in Steam > Properties and add -force-d3d11 or -force-glcore. This can sometimes bypass Windows’ overhead and give a 5-10 FPS boost on older hardware.

Key Performance Parameters

Parameter	Recommended Value	Impact
Shadows	Disabled	Massive FPS gain (CPU & GPU).
Draw Distance	1200 – 1500	Reduces “stutter” while driving fast.
Mirror Quality	Off (0)	Prevents frame drops when looking at the dashboard.
Anti-Aliasing	0 (Off)	Essential for clear visibility on low resolutions.

Conclusion and Expected Results

By disabling Shadows and Reflections while capping the Draw Distance in your pro_preferences.xml, you are stripping the game back to its functional core. You can expect a 40-60% increase in average FPS, the elimination of the “Town Lag” stutter, and smoother driving physics as the CPU is freed from unnecessary rendering tasks.
