Texture Size seems to affect performance by a lot #37

I have received many reports about the Kentucky Car Overhaul severely affecting performance and load times. Looking through the files I noticed that the textures for the vehicles are 1024x1024px which makes them 5-10 times bigger in file size compared to what they would be if they were compressed to 512x512px. This is the Vanilla texture size but also the one used by many other popular vehicle mods - Even very high quality ones such as KI5's cars. I believe the visual difference would be absolutely negligible but the potential performance gain could definitely be felt. This could make this great mod much more accessible across the board.

Some examples with their file sizes:

Compared to a KI5 texture and a Vanilla texture at 512x512:

Load times, yes. VRAM? 6-7 cars having around 1 megapixel PNG texture will only use about 10-20 megabytes of space in VRAM + RAM. NVIDIA GeForce 3 that I used to run with back in 2001 is more than capable of running that.

Coming back to load times, it will get worser from here as we are adding more and more cars to mod. I just can't do much about that its just how it is. Every new thing we add, more space it will take. I won't be going down to 512x512 unless car that I'm doing is small compared to usual car sizes. 512x512 won't cut it for the looks im going.

Thank you for your response! Fair enough, it's your project! I really like your mod, it's just a shame how many people tell me they can't run it so I thought I'd give some feedback here.
