Firstly disable all overlays and see if that helps,
secondly its almost always depth of field and motion blur in graphics settings options.
Thirdly try setting your antialiasing to override 8x EQ SUPERSAMPLING
if you have 50 or 500x antialiasing and too much quality and resolution distant things can blur like a wall of depth of field from too many antialiasing layered over the top of each other. try using a lower count of config.ini
Lastly there are different types of AA like SMAA or TAA or FXAA try out different modes, make sure you didnt turn on morphological antialiasing by mistake in adrenaline control panel.
delete anything in registry in HKEY current user software AMD HKIDs
Try enabling or disabling CAS (fidelityfxcontrast adaptive sharpening) or post processing or enabling RIS (Radeon Image Sharpening) or the game may have a sharpness value
Try upping the RENDER RESOLUTION or finalresolution or your history resolution may be too low. almost always nowadays there is a RESCALE or RESIZE option in graphics menu which should always be about uhh from 0.75 or 0.80 or 0.90 at 4k to maybe 2.0 or 1.5 or 1.3 or or 1.2 or 1.0 at say 1080p. if you've resolution scaling set to too low it can cause this.
maybe you hadnt enabled TRUEFIDELITYFXPROFULLSUPERRESOLUTION2.0 or you arent using say imagequality2 in a config.ini file?

you might be using the wrong drivers. factory reset or uninstall adrenaline and use windows update ones, or make sure you are 12bit FULLRGB 444 and 10bit panel output. try enable or disable VRR and or HDR too or turn antilag on. Install latest adrenaline drivers from AMD.com using the highest graphics card or board model available such as if you've a 6600xt try manually browse and add in the display driver .inf file and dont only show compatible and select 6950xt see if it crisps up. often just after reinstalling drives u must do this again or maybe each reboot.
use windows DVR to record or screen capture or use radeon overlay or use steam maybe in lossless PNG mode? different keyboard shortcuts if layered over the top can be funny
adjust the sharpness in your TV/monitor, use the word TRUECLARITY or FOCUSFALSE or FOCUSTRUE and FOCUSAREA and FOCUSDISTANCE and FOCUSINTENSITY or whatever. Sometimes words like FOVcorrection may help.
edit the .ini files in games and see if theres the wrong settings in there, or maybe you arent truerendering truereality truesimulation and countless other words like truelight?
adjust your windows display settings and refresh rate, if you changed from game mode to movie mode you may not have configured your TV for viewing entertainment as you had for gaming.
oh yeah try some randomizeddithering? i dunno.
if fulltracedpathways helps or fullvectorlightpathways or whatever ensure directx12 mode is enabled or ensure you are using vulkan for applicable titles.
in device manager show hidden devices and remove every monitor and edit registry and remove monitors and try type in monitors false. ensure you arent using adaptive 60fps quality or other trash dynamic quality settings that lower resolution for speed. Disable boost or RSR or FSR.. you dont ever need those actually for 90% of the time.
i forgot in gaming in adrenaline overlay set texture filtering quality to HIGH and ensure in game menu and adrenaline you set anisotropic filtering to forced 16x or if you've turned on too many 16xAF you may need to turn one off if you've say multiple GPU's in adrenaline overlay and its on for both and in game and in config files and in registry and in other ways or places.
