    Radeon Chill Mechanics?

    holl0918

      Normally Radeon Chill doesn't add any input lag, while keeping your FPS between the set values. I want to get the max refresh out of my monitor without adding input lag. FRTC adds input lag and doesn't work well with FreeSync, VSync/Enhanced Sync add microstutters and input lag. If I set my Chill min fps to 72, and my chill max fps to 72, it SHOULD allow me to cap my FPS without any additional input lag or stutters. If I understand how Chill and FRTC work, FRTC adds input lag because it is limiting the FPS the GPU is producing, whereas Chill limits FPS by changing the amount of FPS the CPU is requesting of the GPU (or something like that. IDK how exactly it works, but this is how it was explained to me). If this is true, I should be able to set Chill min/max to 72fp and it will cap my FPS and keep it within my FreeSync range without any added input lag, correct?

          It definitely seems that all cards and all monitors don't work the same when it come to Chill, FRTC and FreeSync.

           

          I know for me I am best to just disable Chill as I get the stutters too. No matter what combination I use as long as Chill is on it just doesn't play nice. So I just use FRTC and FreeSync. On my setup they are working together. I just have to limit the frames to one bellow the max for my monitor. Mine is 75 so I set FRTC at 74. It is working okay and definitely less lag than VSync enabled.

            I run chill but cap it from 50 - 60 & leave it at that & cap my Frame limiter to 60+ no issues. I havnt experienced lag or input lag with chill enabled & its enabled for all games in Global settings. I rather have it active saves an accidental baked videocard. I found with chill running right shouldn't notice input lag if any at all but I am running on an acient monitor. I noticed a lot of chill issues come from chill being set far to high or far to low. I find a point where I rather enable it lower & give myself a 20 frames buffer for the higher limit gives the card active cooloing in theory under load all the time while gaming. Temps barely get to 60deg under heavy load with my RX560OC 4G playing The Witcher3 or even War Hammer Vermintide 2 runs silky smooth surprisingly on 18.2.1 drivers. Every1 to there own on if they enable or use it but if you monitor isnt effected by chill being activated I recomend running it as its handy to have running. Another thing is when running chill find a Game you play a lot & adjust & tweak to suit your gaming needs to what you notice. I run it & recomend running it handy as a safe guard especially on demanding games where a bit more control on cooling helps alot.

              that's all I do it cap frames at a higher steady rate my normal frames are capped at 60fps as it is. The 20 buffer from high to low works well no input lag as on an acient monitor. I sit on steady 60 all the time all games the hight low settings makes chill kick in a little faster holding the temps realy steady under heavy load, its implemented so you dont get the thermal throttling. Works like a charm I even set the boys R7 360OC 2G the same way & hes pulling ultra settings with GTA5 with ease no lag. I use it I recomend it I swear by it its  worth using but chill is more for Keeping thermals at optimal temps. I sue those settings as I dont wanna push my card any harder & like my steady 60fps. The Witcher 3 on Meduim High runs like butter & Vermintide 2 like butter with chill settings from 50 on low to 70 high settings. & main frame cap set on 60 no issues. I will screenshot my settings so can give a example how I use it & how well it works & I play a varity of games as well as other things. I did a lot of reading & research to get my settings where they are & a bit of fine Tuning. I run Killing floor2 on Ultra settings with all game settings manually set in global settings then tuned the same in game. Dont mock it till you try it just comes to finding where your happy it holds steady & I am still on 18.2.1 drivers to boot with that.
