A report published October 13 describes running the DOS version of Quake at 800×600 and a steady 60 frames per second on a Dell OptiPlex 380, using its original software renderer. The piece argues that modern hardware makes high-resolution software rendering practical, while noting that results vary by game and that native DOS setups still face sound-card challenges.
A retro-computing writer says a Dell OptiPlex 380 can run the DOS version of Quake at 800×600 and a steady 60 frames per second using its original software renderer. The October 13 report makes the case that modern processors can run classic DOS games at resolutions that were impractical on 1990s PCs, while preserving the crisp, pixelated appearance of CPU-drawn graphics.
In the report, published on James F. Mackenzie’s website, the writer describes the Quake result as one of the best-looking things he has seen a DOS game do. The account is a personal test and aesthetic judgment, not a comparative benchmark across a range of computers. It gives a specific configuration and frame rate, but does not detail all system specifications or testing methods.
Software rendering means the game’s CPU calculates and draws the image, rather than handing that work to a 3D graphics card. The report says classic titles including Doom, Duke Nukem 3D, Blood and the original Quake were built around this approach. Later accelerated modes, such as GLQuake and 3dfx versions of some games, delegated rendering to graphics hardware and could produce a different visual style.
The writer favors software rendering for its sharply defined texture pixels and visibly stepped lighting, which can result from the limited color palettes used by many games of the period. Those characteristics are limitations by modern graphics standards, but the writer says they contribute to the games’ gritty look. The article also stresses that preference depends on the title: Blood looked better to the writer in its DOS software mode, while Tomb Raider’s underwater sections looked better in its accelerated mode.
Modern CPUs Revisit DOS Graphics
The development described is not a new game release or a change to the original Quake. Its relevance is that faster modern CPUs can make high-resolution DOS software rendering usable, offering enthusiasts another way to experience old games without substituting a later graphics mode. That can matter to players seeking the appearance and behavior of the versions designed for DOS, rather than simply a contemporary recreation.
There is a practical trade-off. In software rendering, drawing more pixels increases the work done by the processor, so higher resolution can reduce performance. The report cites a video by Rasteri showing that some Build engine games remain demanding at very high resolutions: on a Portwell RUBY-9719, a 3.3GHz quad-core Xeon was not quite enough to run Shadow Warrior at 1600×1200. This is an example from a specific setup, not evidence that all systems or games will perform the same way.
The report’s point is also about preservation of an original presentation. Its author says the appeal is not only nostalgia: the original renderer’s sharp textures and stepped color can be part of how a game looks and feels. That is a preference, not a claim that software rendering is technically superior in every title.

From 1990s CPUs to Today
During the 1990s, players often faced a choice between running a game through its software renderer at a low resolution or using a compatible 3D accelerator. The report notes that accelerated releases and modes could alter the image, including by smoothing textures with bilinear filtering. What was once a hardware limitation now creates a distinct visual option for people running the original DOS games.
Some later titles have kept software rendering available. The report points to Ion Fury, released in 2019, as a Build engine game that still ships with a software renderer. It also distinguishes original DOS releases from source ports: Doom and Quake ports can offer software rendering on Windows, but the writer is specifically interested in running the DOS versions on real hardware.
Emulation is another route, but the writer says some DOS games struggle in DOSBox even when they run as intended on original hardware. The article does not claim that every game has this problem. It frames real hardware as the preferred option for this particular effort, while recognizing that assembling a suitable system presents its own obstacles.
“isn’t quite enough to run Shadow Warrior at full 1600 by 1200”
— Rasteri, as quoted in Mackenzie’s report
Performance Varies by Game
The report does not provide a standardized benchmark, full hardware specifications for the OptiPlex test, or independent replication of its 800×600, 60 fps result. Performance depends on the game, resolution, processor and configuration, and the article’s examples should not be treated as guarantees for other machines.
It is also unclear how broadly the author’s experience with DOSBox applies across titles and configurations. The report identifies sound support as an unresolved practical obstacle for modern PCs running native DOS, because such systems generally lack the sound hardware older games expect. It points to sound as a subject for a separate discussion but does not provide a solution here.
Native DOS Sound Is Next
The report ends by identifying sound as the next issue for a modern computer running DOS natively: games need compatible sound hardware or another way to communicate with it. The author does not give a timeline or describe a specific fix, so the next step in this account remains open.
For readers interested in trying the approach, the article names Quake, Duke Nukem 3D, Blood and Screamer as games worth testing, with higher-resolution modes where supported. It also recommends comparing software and accelerated modes title by title, since the visual result is not the same for every game.
Key Questions
What is software rendering in a DOS game?
It is a graphics method in which the CPU calculates and draws the image, rather than sending that work to a 3D graphics card. The original DOS versions of games such as Quake and Doom used software rendering.
What performance did the report describe?
The writer reported that Quake’s DOS software renderer ran at 800×600 and a steady 60 fps on a Dell OptiPlex 380. This is a personal result for one setup, not a general benchmark.
Why does the writer prefer the software-rendered image?
The writer favors its crisp texture pixels and stepped lighting, which can give games a rougher appearance than the filtered image produced by some early 3D accelerators. The report presents this as an aesthetic preference.
Is software rendering better for every classic game?
No. The writer says Blood looked better in its DOS software mode in his testing, while Tomb Raider’s underwater scenes looked better with acceleration. The preferred mode varies by game and scene.
What is the main obstacle to running DOS games on modern hardware?
High resolutions can place substantial demands on the CPU, and native DOS setups also need a way to provide compatible sound support. The report identifies sound as an unresolved topic but does not offer a solution.
