i found the solution I think.

The problem I think it was I was setting a global value.
I set it in an container to load at player login and the lags are gone, also no spikes and CPU cycles are more then low >0,001 in an 40min dungeon.

The Code is:

local EventFrame = CreateFrame("frame", "EventFrame")
		EventFrame:RegisterEvent("PLAYER_ENTERING_WORLD")

	EventFrame:SetScript("OnEvent", function(self, event, ...)
	if(event == "PLAYER_ENTERING_WORLD") then
		ZoneAbilityFrame:SetScale(1.3);
		ZoneAbilityFrame.Style:SetAlpha(0);
		ZoneAbilityFrame.Style:Hide();
		DurabilityFrame:Hide();
		BuffFrame:SetScale(1.5);
		TemporaryEnchantFrame:SetScale(1.5);
		ObjectiveTrackerFrame:SetScale(1.1);
		ObjectiveTrackerFrame:SetSize(260,750);
	end
	end)
		
		
	local cap = ZoneAbilityFrame.ClearAllPoints
        local sp = ZoneAbilityFrame.SetPoint
        hooksecurefunc(ZoneAbilityFrame, "SetPoint", function(self)
            cap(self)
            sp(self, "BOTTOM", UIParent, "BOTTOM", 0, 90)
        end)
		
		
		local cap = VehicleSeatIndicator.ClearAllPoints
        local sp = VehicleSeatIndicator.SetPoint
        hooksecurefunc(VehicleSeatIndicator, "SetPoint", function(self)
            cap(self)
            sp(self, "TOPRIGHT", Minimap, "BOTTOMLEFT", -30, -10)
        end)
		
		local cap = ObjectiveTrackerFrame.ClearAllPoints
        local sp = ObjectiveTrackerFrame.SetPoint
        hooksecurefunc(ObjectiveTrackerFrame, "SetPoint", function(self)
            cap(self)
            sp(self, "TOPLEFT", 40, -10)
        end)
		
-- Slash Command List
	
SlashCmdList['RELOADUI'] = function() ReloadUI() end
	SLASH_RELOADUI1 = '/rl'

SlashCmdList["READYCHECK"] = function() DoReadyCheck() end
	SLASH_READYCHECK1 = '/rc'

SlashCmdList["CHECKROLE"] = function() InitiateRolePoll() end
	SLASH_CHECKROLE1 = '/cr'

The problem I encountered was when playing at uwqhd or 4k some elements like the bufframe were way too small and changing the UI scales just made other elements way too big.

Then I just repositioned some other stuff like objective tracker, zone ability frame, vehicle seat indicator and durability frame because I wanted to have them at an different postion.

Also whilst my research I found some code and varibles which might be useful for someone who is looking for something similar.

--[[SetCVar("autoLootDefault", 1)
		SetCVar("Sound_EnableErrorSpeech", 0)
		SetCVar("enableFloatingCombatText", 1)
		SetCVar("cameraDistanceMaxZoomFactor", 2.6)
		SetCVar("SkyCloudLOD", 3)
		SetCVar("autoDismount", 1)
		SetCVar("autoDismoduntFlying", 1)
		SetCVar("rawMouseEnable", 1)  --raw mouse
		SetCVar("rawMouseAccelerationEnable", 0)	--acceleration
		SetCVar("screenshotQuality", 10)]]--
		
		--[[

		hooksecurefunc("BuffFrame_UpdateAllBuffAnchors", function()
		BuffFrame:ClearAllPoints()
		BuffFrame:SetPoint("TOPRIGHT", Minimap, "TOPLEFT", -40, 0)
		end)
		
		--BuffFrame:ClearAllPoints();
	    --BuffFrame:SetPoint("TOPRIGHT", Minimap, "TOPLEFT", -60, 0);
	    BuffFrame:SetScale(1.5);
		TemporaryEnchantFrame:SetScale(1.5);]]--

--local cap = TalkingHeadFrame.ClearAllPoints
        --local sp = TalkingHeadFrame.SetPoint
		--[[hooksecurefunc("TalkingHeadFrame_PlayCurrent", function()
		TalkingHeadFrame:Hide()
		TalkingHeadFrame_CloseImmediately()
		end)]]--
		
		--[[
		local cap = GroupLootContainer.ClearAllPoints
        local sp = GroupLootContainer.SetPoint
        hooksecurefunc(GroupLootContainer, "SetPoint", function(self)
            cap(self)
            sp(self, "TOPLEFT", 400, -100)
        end)
		GroupLootContainer:SetScale(1.1);
		GroupLootContainer:SetSize(260,750);]]--
		
		
		--CompactRaidFrame1HealthBarBackground:Hide()
		--CompactRaidFrame1HealthBarBackground:SetAlpha(0)
		
		--RAID_CLASS_COLORS['PALADIN']["r"] = 0.83
		--RAID_CLASS_COLORS['PALADIN']["g"] = 0.69
		--RAID_CLASS_COLORS['PALADIN']["b"] = 0.22
		--RAID_CLASS_COLORS['PALADIN']["colorStr"] = "d4af37"

This is what it looks like
