A wrapper for the RRedline Windows API and the Speedy3D DOS API used by the 1990s Rendition Verité videocards, the world's first GPU. Allows Windows and DOS** apps designed for it to run on modern hardware*. Support for the CGL (Cr*ative Graphics Library) API is planned, but not guaranteed. Functions as a 128 MB V2000 (16 MB V1000+*** under DOS) board and is compatible with all 13 RRedline (12 V2.0 && 1 V1.0) apps (10 require no additional open source legacy DirectDraw/Win 98 Memory manager shims. The ones that do, need the free products DxWnd (2.05.99) or dgvoodoo (not supplied)). Detailed instructions can be found here: https://www.vogons.org/viewtopic.php?f=9&t=95721). Support for DOS apps is currently preliminary (alpha). Under DOS ICR2/C*RT2, Wh*pl*sh, vQu*ke 1, R*b*l Moon, N*scar 2, N*scar Racing 1999, and T*m* R*ider are supported (either fully or with minor glitches). Support for the rest and bug fixes will be added in a series of updates. A launcher which can be configured to setup Win98/XP SP2 compatibility for supported apps is supplied as well as two custom builds of Dosbox (Dosbox-Rendition) and Dosbox-Staging( Dosbox-Staging-Rendition) for running DOS apps (also run from the launcher)(source available including for Speedy3D RReady). No RRedline or DOS apps are supplied with this product. However the help file lists hyperlinks from which demos and game patches can be downloaded along with their MD5 checksums. -- Recent updates add support for - 60 fps Frame Generation/interpolation supported for Gr*nd Prix Legends and "D*e by the Sword." Note GPL will have to be run at default resolution/4:3 (fill screen aspect) aspect as the game has a mouse lock. Higher resolutions can be selected from within the game, Your GPU's internal aspect ratio controls from its control panel should be used for aspect ratio selection. "D*e by the Sword" can be upscaled without issue. - Patched version of ICR2 should be used for high poly/detail carsets. See the help file (Click "Help" button on RLauncher.) -Support for a full 16 MB of VRAM for Speedy3D apps. This is the upper limit for Speedy3D (24 bit). For Speedy3D apps, VRAM is configured in dosbox-rendition.conf (or ...-staging.conf) with [rendition] MaxVRAM =nn (nn is in MB, range 4-16, default 16 if setting missing) For RRedline MaxVRAM=nn can be set in rendition.cfg and it defaults to 128 MB - Bilinear filtering can be disabled by adding nofilter=1 to rendition.cfg. Some games might not render correctly with this setting. - Higher resolutions may be selectable in vQu*ke 1, but currently have issues. This will be resolved in a future release. - vH*xen II additional resolutions can be unlocked by selecting the game in the WinApps tab of RLauncher and clicking "App Settings."->Unlock resolutions. There may be rendering bugs with higher resolutions. This will be fixed in a future update. - ICR2 – RLauncher now offers control over fogging, bilinear filtering and low res mirrors (original game resolution). Additionally options to disable line drawing and Rendition Anti-Aliasing are available. The latter two are turned off by default as custom carsets have issues with this, even on original hardware. They can be turned back on for purists. - ICR2 by default disables Rendition anti-aliasing which makes the game runnable on GPUs with less VRAM, such as Intel HD graphics. It also provides a significant performance boost on such systems. - Dosbox-Staging-Rendition now uses dosbox-staging-rendition.conf as its setting file. If an older version was installed, run dosbox-staging-rendition, close it and then copy the old dosbox-staging.conf settings into the newly created dosbox-staging-rendition.conf (use notepad). - Window positioning/centering controls in RLauncher with support from the wrapper. (Note: Position (0,0) is the top left of the primary monitor. Anything to the left/top of the primary will have a negative x/y coordinate or possibly both. **Support for DOS Rendition apps (Speedy3D) is preliminary. Currently a few Speedy3D apps may require (%localappdata%\dosbox\) dosbox-rendition.config to be modified depending on system performance for application stability (when using DMA). Please see the help file (launcher help button ) for details. *** As fast as a modern CPU/GPU can go with a V2000 internal resolution list.(optionally upscaled to native resolutions). DOS apps require a discrete GPU and a fast quad core. * Some GPUs such as the Intel HD 4000 may have compatibility issues with some apps. Discrete GPUs should have no issues.
