Disabling SAM helped me with stuttering

[Borbil Owler]

After many many tries of different recommended ways to reduce stuttering I was desperate. Today I tried disable AMD SAM (Smart Access Memory). After rebooting PC game works like a charm. Absolutely no stuttering even in Hogsmeade. My Specs are R5 3600, RX 6600, 16GB RAM. Some settings on ultra, some high, fog and shadows on med, TAA high, no upscale. With this setting I have constant 60 FPS on FHD everywhere.

I don't know if Nvidia or Intel has something similar to the SAM, so maybe this is only valid information for a team red. Hope this help somebody. Have a nice and many apologize for my english.

Weird. With SAM enabled I do not get issue.

Crazy how one fix works on some PCs but not on others.

Running 5800X and 6700 XT here.

Resizebar

it's called "rebar" (Resizable BAR) and it's been around long before AMD decided to try to call it SAM like it's something new they invented

has to be toggled in BIOS -- it's not typical to have it enabled.

Děkuji za pozdrav do komentáře a doufám, že taky najdeš nějaký způsob, jak tu hru záhadně zprovoznit k tvé spokojenosti :) Dovolil jsem si tě i přidat do přátel, jelikož nemám možnost postnout komentář na tvůj profil.

I used 32gb of ram as 16gb wasn't enough for me

Weird. I'm playing with 6950XT with SAM on. Asides from occasional CTD with RT on in game pre March patch, everything goes just fine. I may try to disable SAM and see if anything changes.

Okay I just tried and disabling SAM actually makes my game stutters. Feels like the game stops for a split of second in regular interval. Tested in Hogsmeade.

"ReBar / SAM" is neither a nvida or amd thing. Its a PCIE-Feature, so yeah, naturally you enable it in bios i you have a new enough CPU. (10th generation Intel CPUs and newer support resizable BAR, as do Zen 3 and newer AMD Ryzen CPU's), and you need a 30-series nivida. FOr AMD you need more: 6000-series card and a Ryzen 5000 or 3000 CPU, except for the 3400G and 3200G models. You also need a motherboard with an AMD 500 chipset or a 400 chipset combined with the 3000-series CPUs

Its been around (In specs) since 2008 (https://pcisig.com/specifications)

I'm on a 4090 and disabling rebar on motherboard has stopped the jitters greatly. This also was a problem in borderlands 3 and the same thing helped. I still see where it does them but they are hugely less and don;t bother me.

I have an RX 6600 with a Ryzen 5600 and this game was unplayable with SAM enabled. I had to also disable 4G decoding.

Then perhaps stop buying new GPU every year or two? New hardware always brings more problems than fixes.

GTX 1070 user here and no problems whatsoever while not expecting 999fps.

Sure, everyone should play and stay with geforce 10xx and Radeon RX 4xx series, that's amazing advice.. 🤦‍♂️ Oh mighty gamer, now I feel so sorry that I have decied to bought newer GPU and replaced old GTX 1060. 🤦‍♂️🤷‍♂️

Holy crap. Okay so i'm on a Ryzen 5 3600 with a 6700XT. My mobo is a Gigabyte B450 Aorus Pro Wifi. I had to turn on "Above 4G decoding" and enable "Resizeable BAR" in order for my games to stop crashing. That is so crazy for some people turning it off was better. My hogwarts Legacy crashes with these settings both on and off but my Vallhalla game will not run if Above 4G Decoding and Resizeable Bar are off. Anyone might know why that is??
