A report published October 13, 2026, makes the case for playing original DOS games with their CPU-based software renderers on modern hardware. The author reports Quake running at 800×600 and a steady 60 frames per second on a Dell OptiPlex 380, while noting that some demanding games still strain fast CPUs and that native DOS sound support is a hurdle.
In software rendering, the CPU draws each frame rather than handing the work to a 3D graphics card. The report says games including Doom, Duke Nukem 3D, Blood and the original Quake used this approach. Later accelerated modes, such as GLQuake and 3dfx modes for Blood and Tomb Raider, shifted rendering work to graphics hardware and could produce a different visual style.
The author prefers software rendering in many cases because its textures look sharply pixelated and its limited-color lighting can create visible bands and hard-edged shadows. Those qualities reflect technical constraints of the period, but the report describes them as part of the games’ intended appearance. The author also stresses that this is a personal preference, not a universal ranking: Tomb Raider’s underwater scenes, for example, look better to the author in its accelerated mode.
The performance example comes from the author’s own setup: Quake at 800×600 and 60 fps on a Dell OptiPlex 380. The report also cites a video by Rasteri about a Portwell RUBY-9719, saying that high-resolution Build engine games can demand substantial processing power. In that example, a 3.3GHz quad-core Xeon was described as not quite enough to run Shadow Warrior at 1600×1200 at full speed. These are specific setup reports, not a standardized performance test.
Modern CPUs Revive High-Resolution DOS
The development matters to players seeking the original DOS versions of older games rather than later ports or graphics-card modes. Modern processing power can make high-resolution software rendering usable on hardware that still runs DOS, offering a way to revisit the games’ original rendering style without the low resolutions common on period machines.
The report also points to a practical limit: software rendering puts the work on the CPU, and each additional pixel adds work. A newer or faster computer does not guarantee full speed in every game or at every resolution. That makes the experience dependent on both the title and the particular system, rather than simply on whether a PC is modern.
For readers interested in preservation, the distinction is relevant because software and accelerated modes can look different. A graphics-card version may be smoother, but it is not necessarily a visual match for the game as it originally ran. The report’s examples show why enthusiasts may choose one mode for one title and another mode for a different game.

From DOS Pixels to 3D Cards
In the 1990s, players generally ran many DOS games in software at low resolutions or used a 3D card for an accelerated version. The report describes a third option now: run the original software renderer on a machine with enough CPU capacity to handle higher resolutions than typical period hardware could manage.
The author distinguishes original DOS releases from modern source ports and native Windows versions. Those alternatives can provide software rendering, but the report’s stated goal is to play the DOS versions as released, on real hardware. DOSBox is another option, though the author says some titles struggle in the emulator while running as intended on physical hardware. The report does not provide a game-by-game comparison of emulator performance.
Software rendering has not disappeared entirely from newer games: the report points to Ion Fury, released in 2019, as a Build engine game that still includes a software renderer. The author recommends trying Quake at 800×600 or higher, as well as Duke Nukem 3D, Blood and other Build engine games at high VESA resolutions. These recommendations reflect the author’s experience and taste.

Performance and DOS Sound Limits
The report does not provide independent benchmark data, system specifications for every example, or tests across a broad range of DOS games. The 60 fps result is tied to one Quake setup, while the Shadow Warrior example is relayed from a video. It remains unclear how other systems and game versions would perform at the same settings.
Native DOS audio is another unresolved practical issue. The report says modern PCs generally lack a sound card that older games can address directly, but it does not detail a solution. The author describes sound support as a separate problem still to be addressed. The article also does not specify which configurations make every recommended title run reliably on real hardware.

Sound Support Is the Next Hurdle
The report points toward a follow-up on sound cards and audio support for fast PCs running native DOS. Until that issue is covered, readers do not have a full account of the hardware needed to recreate the experience from the article.
For now, the author’s suggested next step is to try selected games at higher resolutions on hardware capable of running their original DOS releases. Results will vary by title and machine: CPU capacity, resolution and game-specific rendering all affect performance. No further testing or publication date for the sound discussion is specified.

Key Questions
What is software rendering in a DOS game?
It is a rendering method in which the CPU draws the game’s pixels, instead of relying on a 3D graphics card to do the work.
What performance does the report describe for Quake?
The author says Quake’s software renderer ran at 800×600 and a steady 60 frames per second on a Dell OptiPlex 380. This is a report of one setup, not a general benchmark.
Does software rendering always look better than accelerated graphics?
No. The author prefers software rendering for many games because of its sharp textures and stepped lighting, but says some scenes in Tomb Raider look better accelerated. The choice is presented as a matter of preference and varies by game.
Why not use DOSBox or a source port?
The author says source ports and Windows versions can offer software rendering, but the goal is to play the original DOS releases on real hardware. The report says some titles struggle in DOSBox, without giving detailed comparisons for each game.
What problem remains for native DOS gaming on modern PCs?
Sound support remains an issue: the report says modern PCs generally do not have a sound card that older DOS games can address directly. It does not yet explain a specific solution.
