Hi I´m experiencing FPS Drops in Blood 1. The game is running on 60 FPS but very often drops to the 30-40 FPS and is not good for eyes. How can I resolve this ?
I have GPU: AMD Radeon 7500 Series RAM: 4 GB DDR2 CPU: Quad Core 2,40GHZ
Thank you for help ;)
If you need any other info ask me ;)
I have version from GoG.

Try forcing V-sync via Catalyst control center.

You mean Wait for Vertical Refresh ? And I need to enable it for System Settings or only for the game ?

Yes Whatever suits you best. ;)

I tried that Wait for Vertical Refresh and I think it´s same as before but I set in Dosbox configuration file from svga_s3 to the vesa_nolfb and the FPS is a lot better than before. Is there any other good configuration than this vesa_nolfb for a better FPS with which I get stable 60 FPS ? And can be the problem that I lowered my CPU speed from 3.20 GHZ to 2.40 GHZ ?

Anyone can still help me ? :(

Have you tried any of the experimental DOSBox builds such as the YKHWong build? Styxmaster wrote up a fairly decent review of it a while back.

See: http://www.gog.com/forum/blood_series/make_blood_run_1280x1024_resolution_smooth_did_you_know/post1

You will probably want to just download the most recent YKHWong build, his review is getting a little long in the tooth, but still relevant.
