With SAM enabled there can be anywhere from a 10-20+% increase in performance when working over being disabled. Here are two benchmark runs with the same settings but with SAM enabled and disabled.
This is obviously a good result at first glance. When racing normally the fps is often 90-115 with the same settings with SAM enabled. However at repeatable points on various tracks the frames will drop into the 40s. These drops are the same even after lowering the settings.
If SAM is disabled the frame rates stay between 70-90fps in normal racing, even during the problem spots. However this gives up quite a bit of performance on the top end obviously. It also requires enabling and disabling SAM either through the AMD Adrenaline or the BIOS depending on the game being played. Neither of these options are ideal.
Well since the 5.0 update the repeatable giant frame drops have been eliminated it seems. However it has introduced constant micro stutters throughout races when playing in either unlocked or unlocked v-sync. Which “unlocked” still seems to do nothing with a vrr display. SAM compatibility needs to be fixed as it needs to be on for performance in every other game. Even in FM it gives a great boost although now it’s a stuttering mess. Even on 60 vsync the stutters rear their ugly head.

I got same setup as yours and got nor stuttering problem with SAM tho i play with 5120x1440 resolution all setting manually maxed out, ray tracing off, 100% res scale, and unlocked(v-sync) 75fps lock and everything works fine (I changed monitor refresh rate to 75 cuz 100 get 50fps in multi now)
I’m running full fat raytracing, 120hz, @ 4k. Though even with raytracing off it still persists. I couldn’t tell you why yours is seemingly working however there are many reports of SAM causing issues since the release, for me it was exacerbated with the latest update. This is a completely new machine as well with no other games that exhibit similar issues.
If u change your monitor refresh rate to 60/72/75 Hz, u will get same fps everywhere, and no Sutter’s, when u use 100hz or more, multiplayer mode will have fps limited to half of refresh rate, that make game Sutter and monitor to flicker cuz variable refreh rate cant deal with low fps, basically anything below 72 fps and monitor will flicker when max refresh rate is 120 or more
But there’s problem with multiplayer fps limit, u are basically forced to use 60/72/75 Hz setting in monitor to have smooth fps, if u have anything more it will be halved or even divided by 3 if u have 165 Hz monitor, and from what other players say, it makes game Sutter a lot.
Kind of but not really. If you switch to vsync 60 the micro stutters are way less frequent, limited certain parts of tracks, but they are still there. Also I don’t want to cap my refresh as I don’t play online at all. It’s also not limited to a refresh rate and vrr because turning off SAM eliminates the issue completely although with a 10-20% decrease in performance.
I have my game always setup in way that I reach my max refresh rate with fps in case of Forza 100 fps, and use unlocked (v-sync) option, if I remember correctly, stuttering issues were always present from day 1 with rebar on if u used 60fps(vsync). So yeah it might be problem with rebar/Sam implementation (u get same issue with Intel CPU), but somehow when u use unlocked (v-sync) and limit your refresh rate so that u get stable fps, everything work fine.
i just tested the game again i have zero stutter even with unlocked FPS !!! and there is no FPS drop with AMD SAM on !!! what amazing Update !!! i enjoy the game !!!
Yo tengo un i7-11800H, Nvidia RTX 3060 Mobile, 16 GB DDR4 y 1TB SSD, sigo teniendo considerables problemas de rendimiento, muchas caídas de FPS, es raro que llegue a 60 fps estables, y no es por falta de potencia del hardware, porque da igual en qué configuración gráfica esté el juego, siempre es inestable, creo que va mucho peor en gráficas NVIDIA que en AMD, esta última actualización no mejoró la estabilidad ni el rendimiento pero sí añadió problemas visuales con el DLSS(Que por cierto, desde que el juego salió, nunca ha ayudado a mejorar el rendimiento, el juego va exactamente igual con el DLSS activado o desactivado, solo cambia el nivel de ghosting)
I’m running SAM turned on for over month and did not see any fps drops, so previous problems with rebar were fixed. Idk if memory leak problem with desings got fixed yet, since I’m still paying with desings off.
