My question is how long have you been playing warzone?only curious because some cod updates have in my opinion bogged down some fps ,what resolution you using ,is everything maxxed out?
I have 1080ti gigabyte extreme version owned for 4 years only owner tbut it's watercooled with g12 bracket.The cpu I paired with it is 10900k , however I was using a 8700k and I still got over 170fps in 1080p sometimes even with ray tracing on , 4k usually averaging around 85fps.make sure in Nvidia panel lod is set to allow not clamp ,force mutli thread on ,make sure it's in high performance ,turn off the filtering options ,make sure the gpu profile is set to 1080 ti,make sure physx option is set to 1080ti not cpu .i use precision x16, Id assume your using msi afterburner. try a slight and I mean a slight voltage increase after a decent mem overclock .my cards sits at 2038mhz or core clock and 5613 on mem.when I have had issues in past with frames I would overclock the gpu slightly by slightly I mean 2076mhz core clock and 5800mhz mem clock keep in mind I have alot of headroom because it's watercooled .maybe a really slight overclock on mem.the card might be throttling though,also do a disk clean up admin though,you would be surprised how that copied delivery optimaztions can be in the 2gb range of data ,would suggest driver booster and advance system care for overall system performance,hope I helped
