Hiya guys =)
Well i've done my fair share of searching and research, and was just wondering if there are any proven methods for DOSBox to run VESA graphics games with a decent performance.
Motherboard: Can't remember, it has the AMD 780G Chipset though.
Processor type and speed: AMD X2 5000+ @ 3GHz
Amount and type of RAM: DDR2-800MHz @ ~850MHz, 5-5-5-15
Video board w/ RAM amount and type: 9600GT 512MB GDDR3, latest 181.XX Forceware
Sound board: Onboard Realtek HiDef
Operating system: Server 2008 x64 (Vista Server)
Game name (and version, if applicable): Redneck Rampage, latest "Family Reunion" patched.
Description of problem: General low framerate in VESA modes, occassional "Hitching" when moving from one area to another, explosions, and other misc. "intensive" things
Sound mode used: SB16, 44.1KHz, 16-Bit, 32 Voices, HDMA enabled. All other things (GUS, Tandy, PC Speaker, MIDI) DISABLED.
Video mode (Software, OpenGL, Direct3D, or Glide, and resolution): OpenGL, DDraw, Overlay all tried, at original 640x480 VESA resolution
Version of emulator: DOSBox 0.72 Win32 (binary non-CVS)
Steps already attempted to solve the problem: Everything in the FAQ, Readme, searched for "VESA" on VOGONS, and the DOSBox Wiki
I understand that it is at the high-end of DOSBox gaming, in particular i'm trying the build game Redneck Rampage (I have the Family Reunion double CD pack).
The game installed and played fine, but I have to set the graphics mode to 640x480 (no higher) and using the fullresolution=original is a must for me - if I even set 800x600, with output=opengl or overlay or openglnb, it jerks up every now and then and has a shocking framerate. Even at this 640x480, the game is bearable to play at never reaching higher than 20~25fps.
So my question is, assuming this is a VESA graphics thing, are there any commandline tools or DOSBox config options that could help with this? Would changing soundblaster settings help at all too? They are currently at the 44100, 16-bit, max voices, via setup.exe, but anything lower doesnt seem to help with performance.
Is this really the best I could get? Thanks in advance.
