What are the plug-in chips' caps?

Question

When I was trying to complete the Speedstar quests, I plugged in all of my movement speed plug-in chips to help my chances of winning. However, I got the notification once I plugged a few in that the cap is +20% for movement speed. Are there other caps for the plug-in chips and if so, what are they?

Answer 1

All stackable plug-in chips have hard caps. You won't know these caps until you hit them, but the game will tell you what they are.

I found this Steam thread that has all of these caps listed.

Here are the cap values:

• Weapon Attack Up : +100%
• Critical Up :+30%
• Shock Wave :"very powerful"
• Offensive Heal : 100% of damage dealt as HP
• Ranged Attack Up : +100%
• Last Stand : +100% damage if HP is 25% or less
• Counter : send back 250% damage
• Charge Attack : +400%
• Melee Defense : 80%
• Ranged Defense : 80%
• Anti Chain Damage : 6 seconds
• Resilience : avoid stagger if above 5% hp
• Max HP Up : +100%
• Deadly Heal : recover 100% hp on kill
• Auto-Heal : 18%hp/sec after 4sec
• Damage Absorb : 50% chance to restore 200% of damage taken
• Reset : 50% chance of reviving with 80% hp
• Fast Cooldown : 50% cooldown reduction
• Evade Range Up : +200%
• Moving Speed Up : +20%
• Drop Rate Up : +90%
• EXP Gain Up : +100% exp
• Vengeance : 50% chance that 200% of damage taken is dealt back
• Overclock : slow time for 5.5sec after a perfect evade
• Taunt Up : +500% damage dealt and taken
• Hijack Boost : +9 level for controlled enemies

I may be wrong, but based on a few of the fully listed plug-in chip upgrades I'm seeing on the wiki, it seems like these caps are equivalent to the bonus you would receive from a plug-in chip that has been upgraded to +8.

Answer 2

So far the only 2 caps I know are for:

Drop rate which is at 90%, aka 1 level 8 chip but it's most efficient to use 1 level 4 and 1 level 3 chip

and the EXP gain cap is at 450% witch is 4.5 times the lvl 8 chip.

I found these on the wiki: https://nierautomata.wiki.fextralife.com/Plug-in+Chips

I'll do some more research once I'm able to make strong chips.
