"Film Grain" je problem. Kad ga ubijem u igri na minimum tj na 0 onda radi sve u redu. Zadnji su mi driveri.
E jeboga ti

Ako sam dobro skuzija znaci i tebi ode ovaj hotspot na te vrijednosti?
Đava te odnija pa ti se nisi ništa informira prije nego što si kupija. Recenzije, youtube... ništa?

Citiraj:
AMD also elaborated on what constitutes "GPU Hotspot" aka "junction temperature." Apparently, the "Navi 10" GPU is peppered with an array of temperature sensors spread across the die at different physical locations. The maximum temperature reported by any of those sensors becomes the Hotspot. In that sense, Hotspot isn't a fixed location in the GPU. Legacy "GPU temperature" measurements on past generations of AMD GPUs relied on a thermal diode at a fixed location on the GPU die which AMD predicted would become the hottest under load. Over the generations, and starting with "Polaris" and "Vega," AMD leaned toward an approach of picking the hottest temperature value from a network of diodes spread across the GPU, and reporting it as the Hotspot.

On Hotspot, AMD writes: "Paired with this array of sensors is the ability to identify the 'hotspot' across the GPU die. Instead of setting a conservative, 'worst case' throttling temperature for the entire die, the Radeon RX 5700 series GPUs will continue to opportunistically and aggressively ramp clocks until any one of the many available sensors hits the 'hotspot' or 'Junction' temperature of 110 degrees Celsius. Operating at up to 110C Junction Temperature during typical gaming usage is expected and within spec. This enables the Radeon RX 5700 series GPUs to offer much higher performance and clocks out of the box, while maintaining acoustic and reliability targets."
Ilitiga na naški - u prošlosti je postojala jedna termalna dioda na fixnoj lokaciji za koju je AMD pretpostavljao da će biti najtoplija, pa se na temelju toga vršila konzervativna procjena temperature za throttlanje. Sada Navi ima puno senzora i stvarno znaju koja je najtoplija točka odnosno hotspot, pa se to znanje može iskoristiti za agresivno guranje clocka bez throttlanja.
