I recommend that you make the following adjustments to HDLethalCompany config:
1: EnableAA = true
2: EnablePP = false
3: FogQuality = 3
This should give you good results with reducing the amount of texture and geometry flicker due to Lethal Companies very low internal render resolution (and I don't have to reinvent the wheel implementing rendering changes)
