4 Open-World Titles In Linux vs Windows Benchmark Battle (ACShadows, BLands4, HFW, WWM) | RX 9070 XT

Robert LohrLeave a comment

I had a few games in my sweaty grasp this year that ran rather meh on Linux. In the last game I analyzed, I found out that the Mangohud performance overlay can negatively impact a game’s performance. Hogwarts Legacy stuttered heavily in my first test when I explored the world. This is a behavior that you wouldn’t encounter when just playing the game. I only ran into this issue because I always show the Mangohud performance metrics for my analysis videos.

That sparked a desire to retest a few games. I was already planning to benchmark Borderlands 4 a second time since Gearbox supposedly tuned the transmission for better performance. It so turned out that Borderlands 4 was joined by the robo-dinosaur-tamer Aloy, the two mass murderers Naoe and Yasuke, and the dude who fights with a baby in his arms.

And with that, I welcome you to another Linux versus Windows benchmark battle. This time, with four games instead of just one.

I don’t want to waste any more time beating around the FPS, so let’s get right to it.

I also have a German version of this video.

Pragmata: The RE Engine Delivers! | RX 9070 XT Linux Performance & Impressions (Bazzite 43)

Robert LohrLeave a comment

(World Premiere)

Alright, alright. I admit, I’m exaggerating here. It is true for me, however. The unique thing about Pragmata is its use of the RE-Engine, which is like venturing into new territory for me. I have avoided the Resident Evil games and, by extension, the RE Engine because I’m officially in the scaredy-cat camp when it comes to horror games. As a result, Pragmata shines among the many Unreal-based stars in outer space.

And with that, hello and welcome to a Linux Gameplay Performance blog post.

The Pragmata demo was announced at The Game Awards 2025, and the game is slated for release in April 2026.

Will Pragmata’s launch into the Linux universe be soft, or will the trek to orbit be a rocky one?

Here’s a German version of the video.

AMD Radeon RX 5700 XT Stuttering at 1080p

Robert LohrLeave a comment

Quick note before I go into any details: I did not find a solution for this problem, unfortunately. I’ll be explaining what happened and show frame time graphs as proof.

So, with that out of the way, let’s get into it. I’m certainly not the only one with this issue. If you employ the search engine of your liking you will find many threads covering that topic (like here and here and here and here and so on). Some managed to get it working, some did not. I’m obviously in the latter category.

What happens? From what I found in my research it seems like the RX 5700 XT GPU aggressively tries to save energy if it is not fully utilized. If you run MSI’s Afterburner or any other monitoring software, then you’ll see the GPU load and frequency being all over the place. In general, this is a good thing – if it does not affect perceived performance. And this is where it fell apart for me.

Performance Iterating Directories Revisited

Robert LohrLeave a comment

I have written about the performance of iterating directories before, in the context of Java and its switch from version 6 to 7 that brought with it the new Java NIO API. For whatever reason I felt the urge to do something similar again, but this time I wanted to compare two different approaches to recursively scanning a directory’s contents:

To make things more interesting, I implemented this in C++ using the Windows API and the Qt framework, in C# in combination with its buddy the .NET framework and, for good measure, I also threw in the old Java code from over a year ago.

Update (26.12.2014): I added additional data at the bottom of the article.

C# LINQ Performance vs. Iteration

Robert LohrLeave a comment

It’s been a while since I have written something related to programming. Time to remedy that.

Just recently my interest for the C# language rose again and to get back up to speed with the fundamentals I swallowed all videos of an absolute beginners guide on Microsoft Virtual Academy. Something that has been touched briefly was LINQ and my initial thought was: how’s the performance of that compared to how I would usually write it in C++ – where my expertise is?

Mind you, I’m not comparing C# vs C++, but merely LINQ vs. old-school iteration. Let’s go and find out.

Java I/O Performance Iterating Directories

Robert Lohr1 Comment

A while ago at work we were confronted with the task of creating a directory listing in a Grails application. We’ve tried a couple of approaches, one the Groovy way and one the Java way. Both delivered only a poor performance. A short search brought forth a Stackoverflow thread addressing the issue of slow Java i/o performance with only one real solution: switch from Java 6 to 7. That’s no option at work but out of personal interest I gave it a try at home.Read More »
