When S.T.A.L.K.E.R. 2: Heart of Chernobyl was released in 2024, it marked a triumphant return to a game series that had not been revisited in over a decade. And given how many people missed the post- apocalyptic open world gameplay (it takes place in the large area around the melted down Chernobyl reactor), having the series come roaring back was a real treat.
Our review of Heart of Chernobyl gave the title a perfect 5 GiN Gems with some caveats about gameplay concerns. But given that Ukrainian developer GSC Game World was releasing their game in the middle of an actual Russian invasion of their country, some flaws could be forgiven. But even so, the flaws and performance issues marred what would have otherwise been a perfect experience for those who enjoy the unique environment that Stalker offers which really can’t be found anywhere else.
The 2.0 update to the title is completely free, but it was also released at the same time as the S.T.A.L.K.E.R. 2: Cost of Hope DLC. Developer GSC Game World said it was the biggest addition to the game ever made, and they were right about that. Specifically, the free 2.0 “Back to the Zone” update does not just add a few weapons and quality-of-life tweaks like previous updates did. Instead, it upgrades it to Unreal Engine 5.5.4, reworks lighting and foliage, improves A-Life behavior, adds binoculars, new weapons, fog-based stealth, custom difficulty options, PDA statistics, new Prypiat areas and more than 500 bug fixes, making the base game feel meaningfully different from launch without even touching the separate Cost of Hope expansion, which again, we will review very soon.
I was in the middle of a new playthrough when the update happened, although I was not too worried since GSC said that should not affect anything. They were sort of correct about that. I watched a lot of videos about how people were getting better framerates and smoother gameplay with the 5.5.4 version of the Unreal Engine. I had the PC version of Stalker 2, which I played through the Steam platform, running pretty good before the update, but had lowered some of my graphical settings like shadows and reflections to medium or even low and also tweaked some of the other critical controls like the upscaling engine, V-Sync and FSR quality. So, I was happy with performance, but I was looking forward to the upgrade.
So, I was kind of shocked that after the mega update had finally downloaded and installed, the game looked far worse than before and performed even worse. I was experiencing stuttering just walking around the Rostok base and trying to shop for some of the new weapons. And the world looked very low res or even cartoony, with almost no fine details on things like objects or people. It turns out that 2.0 completely wiped my carefully planned settings, putting them all back to some default that did me no favors.
Unfortunately, I had forgotten how I had things configured before, so I had to go through a very painful trial and error process, bumping up a setting here, changing scaling methods and just about everything else. I would change one thing and then walk around and see if it improved either the graphics or the performance, noted the change and tried something else. Eventually, I found some of my old settings like using FSR 4 for quality scaling and Intel XeSS for frame generation, an odd combo to be sure, but one that let me play with high textures and object detail, with other less important things like shadows and global illumination on medium. I was even able to bump up a few things that were lower before, like foliage. This process took about an hour, but it was worth it.
Once I got my settings sorted, the game world really did look better, especially for things like people’s faces. And more importantly my performance greatly improved, especially in the open world. Before when I would get ambushed by rats or snorks, it was difficult to make precise shots. Some of that was nerves, but also my aim kind of slid around a bit, moving too far or too slowly when it counted. Now, however, everything was smooth and precise. I took out a whole gang of rats while backpedaling with my semi-auto rifle and landed accurate shots on each one. The same thing happened with a snork ambush, although I was using a shotgun and missed a few times, but only because those things are really scary. Performance wise, everything was smooth.
So, in terms of performance, I would call the 2.0 update a huge win for PC players. If you already had good performance, it will be better now (after you readjust all of your settings). And if you had great performance, well, more of a good thing is an even better thing.
The other changes in terms of graphics are cosmetic, and whether people like them or not is going to be a matter of taste. Before, the Zone was pretty gray and lifeless looking, which I thought rendered itself nicely to the setting. After all, the Zone was created because of a nuclear meltdown that allowed monsters and anomalies to spread into the area making it very dangerous for people. Now, however, Spring has come to the Zone it seems. Many areas are now green and blossoming, and the forests are thick with foliage once more. I have even seen double rainbows more than once while exploring. At first I hated those changes, but the idea of a slightly happier-looking Zone where life is starting to return is growing on me.
In other environmental news, fog is now a full gameplay mechanic, not just visual atmosphere. First off, the fog rolls in a lot now. I’ve especially seen it in places like the swamps where you would expect that kind of weather. In fog, both players and enemies see and hear less, which can create more opportunities for stealth. The Zone also regularly gets light rain now (which might be fueling all the greenery). That tends to add atmosphere and brings back some of the gloominess without triggering one of those full blown storms where lightning strikes are nearly as dangerous as random anomalies. All of that makes the Zone seem more alive, which is great. And because of the improved performance, things like fog won’t drag your frame rate down to a crawl either, which might have been why it was not really implemented before.
As for the new weapons, many are locked behind the Cost of Hope DLC, but there are a few that were added with the 2.0 update. Specifically, update 2.0 added four weapons: the Arev assault rifle, a GP3A designated marksman rifle, an SKP designated marksman rifle and the Fora-230 submachine gun. A new 3x scope is available for Western-bloc weapons with a new red dot sight for Eastern-bloc ones. Offset aiming is also no longer limited to night-vision goggles. I don’t personally like that since I tend to like to scope down on things, but if you do, and especially if you have a good laser sight, then you can aim that way with anything now.
I tried the new weapons, and they are pretty good. I especially like the new carbine rifle. At the point in my playthrough where I was at when the update hit I already had a Dnipro, which is the Ukrainian bullpup assault rifle based on the real-world Malyuk, Ukraine’s contribution to the Kalashnikov family of rifles. I grabbed a busted one off a dead elite enemy, brought it back to a technician and spent thousands of credits repairing it, souping it up and adding attachments. It was thus fully upgraded with a silencer, extended mag and a good scope, so nothing is really going to beat that. However, for a new playthrough, getting ahold of one of those new rifles early would be a game changer.
I already loved S.T.A.L.K.E.R. 2 before Update 2.0, even when I had to forgive some rough edges, strange technical issues and the occasional mutant appearing somewhere it probably should not have been. But after spending more time in the newly updated Zone, I think this is the best the base game has ever felt. Getting my settings back into shape was annoying, and I still prefer the older, gloomier atmosphere in places. Even so, the smoother performance, improved visuals, better weather, new fog mechanics, expanded arsenal and stronger sense of life in the Zone make this a massive improvement.
For new players, this is the right time to step into Heart of Chornobyl. For returning Stalkers, Update 2.0 is a very good reason to load up your rifle, check your detector and head back into the Zone.
