How to Improve VEIN Server Performance Using Engine.ini Print

VEIN servers can experience low server FPS or stuttering during heavy gameplay, especially with large player counts or high zombie activity. You can improve performance by applying safe and verified Engine.ini settings using official CVars. This guide covers effective performance tweaks for VEIN v0.022h8.

Works on all HostByte VEIN servers. Updated for VEIN v0.022h8

Step 1 Open Your Engine.ini File

Performance related CVars must be placed inside the Engine.ini file under the [ConsoleVariables] section.

Navigate to:

Vein/Saved/Config/LinuxServer/Engine.ini

Find or add:

[ConsoleVariables]

Step 2 Improve Zombie AI Performance

Zombie AI is one of the biggest CPU costs on VEIN servers. These settings improve efficiency without changing gameplay significantly.

vein.AI.AsyncSensing=1
vein.AISpawner.EnableVirtualization=1
vein.AI.EnablePathUpdates=1
vein.AI.PathUpdateRate=0.5

• AsyncSensing moves detection to async threads
• EnableVirtualization reduces AI updates for distant zombies
• EnablePathUpdates ensures efficient path recalculation
• PathUpdateRate adjusts how often paths are updated

Step 3 Reduce Rendering and Lighting Costs

These CVars disable visual features that dedicated servers do not need.

r.VolumetricFog=0
r.Fog=0
r.ShadowQuality=0
r.ViewDistanceScale=0
r.Lumen.HardwareRayTracing=0
r.Lumen.Reflections=0

• Disables fog processing
• Disables shadows completely
• Minimizes view distance scaling
• Removes Lumen based lighting overhead

Step 4 Reduce Physics and Movement Replication Load

p.NetEnableMoveCombining=1
p.NetUsePredictiveOverlaps=1
p.NetUseClientPreReplication=1

• Move combining reduces network movement spam
• Predictive overlaps lighten collision checks
• PreReplication helps optimize movement prediction

Step 5 Improve Garbage Collection and Memory Usage

gc.TimeBetweenPurgingPendingKillObjects=30
gc.AllowParallelGC=1

• More frequent cleanup of unused objects
• Parallel GC improves CPU threading efficiency

Step 6 Network and Replication Performance

net.UseAdaptiveNetUpdateFrequency=1
net.IsStandbyCheckingEnabled=0
net.PingExcludeFrameTime=1

• Adaptive update frequency reduces bandwidth load
• Disables old standby detection that impacts performance
• Removes frame time influence from ping calculations

vein.AISpawner.EnableVirtualization=1
vein.AI.EnablePathUpdates=1
vein.AI.PathUpdateRate=0.5

r.VolumetricFog=0
r.Fog=0
r.ShadowQuality=0
r.ViewDistanceScale=0
r.Lumen.HardwareRayTracing=0
r.Lumen.Reflections=0

p.NetEnableMoveCombining=1
p.NetUsePredictiveOverlaps=1
p.NetUseClientPreReplication=1

gc.TimeBetweenPurgingPendingKillObjects=30
gc.AllowParallelGC=1

net.UseAdaptiveNetUpdateFrequency=1
net.IsStandbyCheckingEnabled=0
net.PingExcludeFrameTime=1
